Hi again,
Really not bad stuff, i think you need to be a bit careful using melody in games as lots of repetition will get annoying for some players, so maybe use the piano more sparingly, and have longer sections without melody, maybe add a B section with some different chords/harmony to give some variety. The pickup sounds are in key with the music which is nice, maybe expand that by having a set of different notes that are played randomly when you eat something, since the player will be hearing that sound a lot and variety is a good thing.
Also if you can think of ways to change the music when different things happen in the game, that's also a good way of making the music feel more involved rather than being something that feels 'in the background'
Kep up the good work!
