Wow, you actually made a working platformer in GM lite. It was already hard enough for me to do it in the pro version!
Now, about the game:
What I liked:
-The evolution options seem to be really extensive and the character is really customizable, I was positively surprised when I evolved the first time.
-The graphics look really nice, I like the character's sprite (and how it changes according to the evolution choices)
What I didn't like:
-The background music is looping too fast. No sound effects.
-Attacking didn't do anything.
-I wasn't sure how to eat, graphical feedback would have helped.
-The choice of keys is poor. I play on a german QWERTZ Keyboard, so the z and y key are swapped, which makes playing this game very uncomfortable for my left hand.
Anyway, impressive work for 48h.
