The game is hampered by its controls. I couldn't figure out until the lizard stage why jumping was so unresponsive, and having the character bounce after they land makes no sense. Being able to land on top of the evolution points is also confusing.
The idea is interesting, but the execution is flawed. You're supposed to be evolving, but going from a fish to a frog to a lizard to a rat to a dog to a human makes no sense at all.
I don't want to be mean, or discourage you from game development, but this game needs a lot of work. Good luck in your future endeavors!
