Hey there! This was an interesting puzzle game!
At first, I didn't really know what I was doing XD (probably because I jumped head first without reading any instructions), but once I understood when I'd switch turtles and when I'd mutate them, the game became a lot more interesting.
Don't take my initial confusion as something bad, but do take the fact I was able to figure it out by myself something really good. Anyways, great job!
