The idea is nice and interesting, but I have the feeling it doesn't work, by now. You move to slowly in an open scenario where the food can fall far beyound you.
Personally I would had choosen a closed area, with no scroll at all, making the character faster, and the amount of food (and other things) falling increasing over time, making the game more and more difficult to handle.
Anyway it is a nice submision. I'm sure that if you desire to work a little longer on it it will work better.
