Nice game, but a few annoyances don't make it catch on to me. First, it is way too cluttered -- I can never pay attention to my actual location. and second, the whole timed-powerup thing.
The controls are a bit confusing at first, but I guess they're fine. It's hard to grasp the finer details of the auto-aim, which usually doesn't aim right. Also, the conversations take way too long at times, maybe add a button to only skip the current sentence?
This isn't as hard once you practice. But the fact that my keyboard doesn't register the space key and the up key at the same time makes it a lot more difficult than it should be... (high score: 321)
