Hi! I think I enjoyed the game more than I should HAHA...
I liked the mechanic where you move slower after eating too much. I think the risk vs reward mechanic is interesting there. I would have preferred moving faster instead of slower when you become hungry. I think it would be in line with the risk reward mechanic since good players can go for a speed boost in exchange for running the risk of dying of hunger.
As it's a 3D game, I think there were times where it was hard to tell whether I could make a jump. You can consider showing a yellow circle below the penguin every time it jumps!

I think the music fits well! I like the general vibes of the game. I think this game will be crazy fun in multiplayer since u can throw bombs and rocks onto your opponent to sabotage them HAHA!
