good game surprisingly fun to play, nice concept. A little bit smoother controls and other improvement can make this a pretty good game. I fell through rock sometimes and that sucked but on the other hand i cheated me up at some points i guess i did it how it was not intended to be done ;). keep working.
Retro is fine that game is fine but please add something, that 1 shot until hit thing is outdated. Better add no sound than that, good start but polish it up.
I guess many give up before they find out how it works and what to do. For all those that are interested.
The Sperm moves itself. All you can do is changing the parameters through evolution points. Speed trait is not the key trait. Your starting position is random so you may win relatively early by luck and lose relatively late by having a bad position.
Simple is good, but this is too simple and too little interaction for me 2/5
