This is... not good. Gameplay is incredibly simple and confusing. Layering problems are all over the place so it's hard to see where you even are. Ground texture flickers at the default window size and is extremely eye-straining if you don't fullscreen. The game lags like hell; I have a gaming PC capable of running several modern generation games, and I was getting single-digit framerates from this game because there was so much on screen at a time.
Finally, and worst of all, this has absolutely nothing to do with evolution.
