This is my game for the compo, Some people say that the last levels are to hard. What do you think?

This is “You only get one piece of food” which is a simple adventure game. The goal of the game is that you have to take yourself through all the levels with just one piece of food per level.

Please tell me what you like and dislike about this game (my first ludum dare)
