I see what you tried to do here - it was a really neat usage of the theme. But this game is missing on player feedback.
It's hard to tell what's happening (for example, I took a long to time to realize that mutations didn't pop up every single turn - that happened because the advance turn button has no feedback besides the sprite changing, so I thought it wasn't even working at all). The lack of feedback also applies to mutations. I had to figure out what each one did all by myself by analyzing their icons and watching the stats change. And even then, I don't think I can tell what a single one of them do.
This game has a lot of potential, but the lack of info really drags it down. I really want to see this game being worked on a little more. Definitively will try it out again anytime soon!
