Cat x11 is an incremental game that does a lot right, but way more wrong in my opinion.
The basic "combat" / material gathering is well done and feels really satisfying, but the other parts just don't hold up. The upgrade tree doesn't feel that balanced. You will get upgrades for a few coins that have a high return on investment and basically print money, and then you have upgrades that cost like a thousand coins and do basically nothing.
The game has a skin and crate system, where you can use the code from other players to get new skins. But... Why? The implementation doesn't really do anything for the player! Either you enter 50 different codes and get a few skins that are basically useless to you, or you don't and just open the three free chests that you get and maybe get something in those. The concept is flawed and in my opinion the biggest problem is that it exists at all.
And my biggest gripe with the game: It's repetitive like nothing else I've played. I mean, sure: When you play these mini incremental games you have a lot of "runs" that are roughly the same every time. But with Cat x11 you play through the skill tree once where the currency is coins. After that you prestige and now the currency is both coins and bread. The skilltree is slightly different, but only really the order of unlocking certain upgrades has changed. And after you prestige again, you have basically the same thing again, but now with coins and juice. If you want 100% achievements you are basically done after not even 45 minutes but you have to replay the game two more times to get fishes as currency. I often continued playing mini incremental games after I got all achievements to finish the skill tree, get a new highscore or at least to see how efficiently i can now destroy everything in my way. Not with Cat x11. Because why should I? I saw what the game had to offer within not even half an hour and then bascially repeated everything until I reached an arbitrary point of prestige.
This was okay for the first 30 to 45 minutes. Everything after that just felt like filler to me.
