Am I playing as a bad guy during an obesity crisis? That's just silly.
I like the theme, but you could do more with it. I like the idea of using the ground bomb wisely, and I like how easy the game is too because it's not infuriating.
I would focus on the audio of the game, it seems a bit bass heavy and there is a lot of artifact.
Edit: Oh, one more thing, I don't like the ambiguous borders because I prefer to touch the edges of my screen with my ship.
