I actually liked the almost everything about this game. I think it had a very retro-future look, similar to Tron and other "futuristic" games of the 80's and you took that theme and went full on with it! The laser sounds the music levels were all really balanced. The only issue I had with anything was bullet time for some reason made the mouse control backwards, so I would have to move my mouse to the way I wanted to run but I was shooting backwards, which makes some sense but was jarring the first time I encountered it.
If player health plays little importance and more of the game is about battery life, I suggest a few more battery placements. Also, I like the use of big capsules giving you bigger lasers... had a homage to Pac-Man in a way. Either way I think with what time we had you made a very solid game!
