Fun game and the fly and eat mechanic make the platformer way more interesting. The fly mechanic feels a bit janky tough. Two things that would probably make it easier to control (in my personal opinion, this is your game, of course): Firstly, Making it so that you already start flying the first time you press space so you don't need to time it during the short time your in the air. Secondly, maybe making it so you glide way more when you hold space in the air after flying up.
Still, good job!
