Love the art style! And the procedural generation is very impressive, although it occasionally leads to some unfair situations. The gameplay is solid and I like the day/night cycle but it can be sometimes hard to see spikes during the night due to how dark some areas get.
My only other critique is that, while the autokill process is cool, a way to manually exit the game aswell would be appreciated so that i don't have to either wait 30 seconds or end it in ol' Task Manager.
