Very nice idea! I think the game need just a bit more polish.
- The stats display is barely visible - (make it white?).
- The death looks a bit like the game is about to crash - (maybe the slowdown should be smoother?)
- Particles look samey - (add some variation to their sprites?)
- It lacks post processing - it can really add a layer of depth to a game
Loved the music and the concept in general. Nice entry :)
