Reminds me of Nitrome's Worm Food.
Personally I'd add a clear goal that has something to do with specific spots in the level, be it hitting targets like in Worm Food, turning it into a platforming challenge where you need to get to a specific spot, or something like that. However with some more polish and a clear indication of how and why you get points, it might work as just a "style" game.
In regards to controls I'd love to have a bit of air control and perhaps control the game with the mouse.
