I liked the idea! Could have been executed a bit better, but still fun. The beginning could have used the small weak creature avoiding danger for a bit rather then just fall and if you hold left or right you are stuck and lose. maybe a different creature who pops out of walls on a timer or something? Only other thing is the weird ghost thing back near the beginning? no explanation just kind of kills you if you happened to remember there is a evolution point up there shown to you right at the beginning.
