Very well done! The only complaints are that the fly scream is a touch too loud, and that the tongue responsiveness is a little weird- sometimes it doesn't always come out when I click. The art is gorgeous! Your style is very unique and cute, and everything from the art to the game design shows incredible potential.
Edit: I really enjoyed the mechanic of chaining together bug eating and building up a sort of combo gauge. Perhaps this could be expanded upon by making it so that you need to chain fast and well enough in order to get a better rank at the end- kinda like DMC?
