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.
