60 of 153 · most liked firstI'm mixed about this game. The concept is great, but the game fails. 1. If you manage to survive, the lag will make the game unplayable. 2. If order to survive you have to expand fast, the higher the difficultly level, the faster you have to expand which makes the game very challenging. The problem is over time your base will become HUGE making it very difficult to manage during night attacks when you can't built while pausing the game. As the monsters break through your defenses, you…
negative · reviewer's own thumbsView post →Awesome fun game idea. No resolution/ui scaling options, so on a 4k screen it causes UI element text to be tiny. Not worth the headache and damaged eyesight to play. So unfortunately I'll refund.
negative · reviewer's own thumbsView post →It was a very Good Game in the first 2 hours, but it became a bit boring afterwards.
positive · reviewer's own thumbsView post →It's cheap and okay but quickly becomes pretty repetitive.
positive · reviewer's own thumbsView post →Pretty basic, not a lot of planning involved and the basic mechanic of the game is to add more and more sprites just lag your computer out until you can't progress anymore. They give you options to turn off the sprites but calcs are still being run in the background so it eventually catches up with you regardless
negative · reviewer's own thumbsView post →If Steam reviews had a 'maybe' option I'd apply that here. Not a bad game, but I found it very sterile.
negative · reviewer's own thumbsView post →Honestly this game is super captivating once you get into it, you start and you just cant stop. Defo get it on sale
positive · reviewer's own thumbsView post →Quickly hits a point where there's nothing else you can do. There's a hard limit on how many buildings you can place, so once you hit that limit, you basically just.... stop. Very cool game idea. Unfortunate they artificially capped it this way.
negative · reviewer's own thumbsView post →enemies AI is stupid. After 20 min you can try to analyze the movements and beat the game
negative · reviewer's own thumbsView post →Just not a good game when it comes down to it. The "networks" for resource transport are more of an annoyance than anything else, and it becomes super laggy even after they are replaced. I ran this game on a 12 core dual thread 5000 series CPU, and a 3070 TI, with 32GB of 3600 DDR4, if you don't have at least these specs, just don't buy it. Also building is alright at first, but it quickly becomes annoying to expand and build the same things again and again, lacks variety, keeps you busy for…
negative · reviewer's own thumbsView post →The free game doesn't save. Good game anyway. (ignore my playtime, got it like yesterday.)
positive · reviewer's own thumbsView post →Fun concept that can entertain you for a bit but couldn't captivate me for very long.
negative · reviewer's own thumbsView post →fun time killer. Pretty intense late game as well.
positive · reviewer's own thumbsView post →It's fine enough for the price but plateaus in complexity pretty early and leaves you wanting a bit more. If I could rate this as a "meh" I would. Probably invest your time elsewhere like the Creeper World series or Mindustry.
negative · reviewer's own thumbsView post →An okay game. The game concept overall great just a grind the only killer is the games optimisation it recalculates all the transfer network when you add or remove nodes or structures so i was forced to wait a over a minute until the recalculation is done cause the game slows down. Just the network system needs to be reworked to only update nodes that need to be updated instead of recalculating the whole network again would make this game bearable. Would i recommend? No you can find better…
negative · reviewer's own thumbsView post →Great fun game, love the web version, and as of writing this I'm on day 310. On higher days, past roughly 250, it gets pretty laggy. I have a good machine and it gets 6 fps on late days (on 2x speed and with all optimization features turned on in the settings.) On early days and the 100s it gets great fps though. Other than fps on late days, its a great game and good to leave on in the background. 9/10 Would Recommend
positive · reviewer's own thumbsView post →you will probably master the game in 15 minutes, and then realize it's literally just about building as much as you physically can, and then waiting for the resources to come in to be allowed to build more in waves. enemies take far too long to pose any kind of threat, and as long as you just keep expanding the only limit is your patience.
negative · reviewer's own thumbsView post →this review is biased. The game is great but in the long run it can get pretty laggy and if you dont have a good pc then you'll be having a slow fps, all in all its good
positive · reviewer's own thumbsView post →Still can't wrap my head around the fact that I played 6.5 hours of this on the first try, in between my workload and waiting for some tests to complete. A very simple, rewarding and repetitive game :-D
positive · reviewer's own thumbsView post →goo game for 1$
positive · reviewer's own thumbsView post →simple, fun and fast growth
positive · reviewer's own thumbsView post →It was nice revisiting this game years later. It is still an enjoyable experience and you can see how many modern games have taken this seed and moved it forward. Still worth picking up if you do not have it in your collection.
positive · reviewer's own thumbsView post →Fun game and for the sale price a must by for anyone who likes tower defense, and resource management. Its a small scope game I paid less than a dollar for. Great for listening to a podcast and shooting zombies. Cons - camera is wonky and never zooms in where I want it to - Laaaaaaaag builds as you get further in. Game has setting options to patch this, but no real fix. - multiplayer? there is a leaderboard but it never really seems to work. Also a chat, but can't seem to chat. - you quickly…
positive · reviewer's own thumbsView post →Extremely unbalanced game, basically impossible to lose.
negative · reviewer's own thumbsView post →really good, but super repetetive, used to play the web version for hours when i was younger
negative · reviewer's own thumbsView post →I give this about a 3 out of 5 stars. I love these types of games and it did entertain me until i lost at around day 50 but no matter how many transporters i used, i couldnt get distant crystals or resources to move back to the base so I was limited to what I could build/defend with. That being said, I feel like a smaller, more densely defended base would work better in this game anyway so trying to reach distant resources is kind of pointless since theres a limit on weapons deployable.…
positive · reviewer's own thumbsView post →This game is such a small gold nugget. The gameplay is very good, especially early on with a very neat spin on the good ol' io games and tower defense with the simplistic and dynamic logistic. I haven't had any performance issues with my Ryzen 5600x yet, and I don't think since I've max seen 20% usage on any thread. The teleport upgrade will probably make sure it won't be an issue extremely long into a game. I do wish the zombies had a stacking limit and would spread out across your walls…
positive · reviewer's own thumbsView post →The game is fun but runs really poorly. After about day 200 the game becomes almost unplayable without pausing the time and waiting for it to load in your base whenever you move the camera. There are some limited options to improve performance of the game however their effect isn't notable. The game is missing some QOL features and while the "advanced ui" shows resources it fails to show things like ammo production vs ammo use. Would be nice if the game could be improved.
positive · reviewer's own thumbsView post →You know what? It would be kinda fun in 2 player but after all super fun. (I played most of the time on web page)
positive · reviewer's own thumbsView post →It is a pretty good game, however you can play it for free on browser. This game is no longer updated. I would recommend this game for a quick play, but you really can't get more than an hour or two of fun out of it unless you enjoy the simplicity. Other than that, it's pretty much just what it seems.
positive · reviewer's own thumbsView post →Good relaxing TD expirience

positive · reviewer's own thumbsView post →its fun for a while
positive · reviewer's own thumbsView post →Great game for those who like to build bases. The only bad thing about this game is it can get very laggy in later stages of the games. Otherwise great game with great mechanics.
positive · reviewer's own thumbsView post →This is a very basic tower defense game with supply lines which means you have to build a couple of transfer nodes and that's pretty much it. There is pretty much no depth to the game beyond this. You should really check the free version online because it feels inferior to most games like this on steam.
negative · reviewer's own thumbsView post →Best tower defense I've ever played, you can play for hours without getting bored and the difficulty curve is perfect
positive · reviewer's own thumbsView post →AM I FLYING A PLANE??? WHAT AM I DOING
positive · reviewer's own thumbsView post →I've played this game since around 2017-2020 on the web version and finally rediscovered it, now on steam and I have to say, the web version is exactly the same don't buy it. Although it is fun, its just not worth it.
positive · reviewer's own thumbsView post →fun little game that turns your pc into a space heater at high levels. Makes you feel smart for doing well, but with a good difficulty curve that is not punishing. base builder tower defense rescource management game
positive · reviewer's own thumbsView post →not really uh.. fun? flop, could've been designed better.
negative · reviewer's own thumbsView post →YORG.io is a deceptively deep strategy experience that fuses tower defense, base building, and logistics management into a tight, endlessly replayable loop. Developed by Tobias Springer and published by tobspr Games, the game challenges players not just to place defenses, but to design a functioning economy capable of sustaining those defenses against an ever-escalating zombie threat. What initially looks like a minimalist survival game quickly reveals itself as a careful exercise in…
positive · reviewer's own thumbsView post →Great minimalistic base/tower defence game, with surprising depth and difficulty (if you want to play on higher difficulties). It feels great for the first time you play it but then for me it got really tedious really quick. The constant expansion means you need to re-organize the base a whole lot as you go, and it got to the point where it's more work than fun. Other than that, great game for great price point.
positive · reviewer's own thumbsView post →absolutely f*cking amazing game would absolutely recommend to people who have more than 1 brain cell to spare
positive · reviewer's own thumbsView post →This game is incredibly engaging once you dive in; you start playing and find it hard to pull away. It quickly reaches a stage where your options become limited. With a strict cap on the number of buildings you can construct, once you reach that threshold, the gameplay essentially comes to a halt. It's a fantastic concept for a game.
positive · reviewer's own thumbsView post →Kudos about having logistics included, but little too basic execution. Tobias have made refined games with same premise making this obsolete.
positive · reviewer's own thumbsView post →Got it on sale for .79 cents, I feel like that was a fair price. Late game play isn't very enjoyable; walls get destroyed, you rebuild them, repeat.
positive · reviewer's own thumbsView post →mmmmmmm zombie fight wall. i like that. very cool. mhm mhm mhm. pew pew PEW goes the cannons. its crazy. i reccomoemend.
positive · reviewer's own thumbsView post →I can get lost through time while playing this. A simple yet addicting gameplay.
positive · reviewer's own thumbsView post →I payed 5$ for it, than I found out you could play practically the same game for free. Was also a bit boring for me. In my opinion, buy it only on sale.
negative · reviewer's own thumbsView post →This was a ton of fun and excellent value.
positive · reviewer's own thumbsView post →https://youtu.be/qZzzDKiQUXY Extremely minimalistic presentation focuses the player attention on the gameplay systems that work surprisingly well after a bit of discovery.
positive · reviewer's own thumbsView post →I actually liked it!
positive · reviewer's own thumbsView post →its good but when u play over 300days. it get realy laggy
positive · reviewer's own thumbsView post →3/5 Pretty simple and could be a bit more refined. But overall it looks good and can be a bit addicting.
positive · reviewer's own thumbsView post →One of the best TD's I've played.
positive · reviewer's own thumbsView post →easy to play not bad for a cheap game it can be addictive
positive · reviewer's own thumbsView post →Fun game - but it's missing a *lot* of QoL features for me to suggest it as something to invest your time in.
negative · reviewer's own thumbsView post →Didn't give this game enough love hours wise, but with what I played, it was fun and I like the idea
positive · reviewer's own thumbsView post →Fun casual of bored
positive · reviewer's own thumbsView post →I think I paid under a dollar for this but like don’t bother
