Very juicy, very nice looking!
Unfortunately, the game has a major design flaw - it can be cheesed by simply going around the map. You should prevent this in you mechanical/conceptual design, very early in the development. Also, you should warn the player that the deflector is about to end, it ending abruptly and making the player bite the bullet could be frustrating I imagine. The slowdown, while nice, serves no purpose when you cheese the game.

Yep, I agree, the biggest flaw is that players can run around the sides of the map and still be able to rack up score easily. I still can't find a way to motivate players to move towards enemies although you should note that enemies cannot shoot at you while you're close. As for the part about the powerups ending abruptly, I was aware of that issue, so I fixed it immediately after the jam. I'll release an update once the voting period is over. And yes, slowing down time is useless when you're not dodging bullets.
