I love the originality of the game's theme and mechanics. The slow down feature makes you feel like in an action movie.
I don't quite get what the enemies are, and the graphics and sounds have room for improvement in my opinion. I also think the game becomes a bit repetitive after a while, so maybe adding a bit of an increasing curve of difficulty would improve the experience.
Interesting feature/bug is that the one time I didn't (or barely) touch the controls, I made my best score (41) getting plenty of health packs and killing many enemies without me doing much.
I think this game idea has potential.
