WOW this is definitely special ✨
Really love the premise and the feel of the gameplay, tho I do think it is a bit too easy. but maybe that's just me or I haven't played long enough, but definitely at the beginning it felt easy, and the terminology with the upgrades is quite confusing at the beginning but I did slow understand what things do, I'd suggest some sort of terminology summary baked in to the game. Also the mixel problem, it's a nitpick but it does take away from the game a bit.
Overall solid base for amazing game, keep working on it and you'll have something special here, great job!
