This game is as fun as it is buggy, one of the species always gets stuck outside the world boundries, if one of them dies the first time you buy a new one it looks like it's completely evolved, but then it moves to the first level again. The waves start only if you buy the sythe, and after the third wave i stopped getting my money. And also it is irritating that they stuck with each other and you can't feed one of them. I almost lost one of the wave because i couldn't buy food because the stall wasn't giving me interaction properly. But overall, i can see a lot of potential here!
