Brilliant. Simple but very well executed. Very satisfying gobbling up all the bugs while avoiding the things trying to eat you. I liked the various different levels with different challenges.
I did see one very minor bug (other than the intended) where I went into the next level and was in a flying state in the next level but previous level I was walking - my wings stayed in a non flying state. Very minor and aesthetic bug.
Great work. I wonder how you could expand it and create more levels with new mechanics.
