The game shows the idea and concept pretty well! You become fatter whenever you eat things like burgers, pizzas, it's really creative :D
The level tiles are sometimes placed weirdly, but I don't blame. Each level kinda explains what you should do and not do during the game. However, the one thing I would like to change is the text to be shortened so that the player doesn't get bored during the gameplay (but I do like a bit of narrative). I like the music though, kinda give me those Ujico - Snail house vibes.
Good job :D
