very cool.. good transitions, nice short iterations (although the Get Ready is kind of tedious after a while). I like the weapons and teleport/slow downs, and level design a lot. Looks like you can probably get really advanced levels...
At first really didn't like the mouse control, but after a bit I got used to it. In general, mouse games don't feel like games to me - I don't know why. I mean, to use a mouse as a way to interact with the interface, sure. But to make my space ship be wherever the mouse is? feels like the ship is really just my mouse.. I don't know, something is weird about it. But like I said, I got used to it.
The WASD keys should rotate the ship in the direction rather than it just popping to exact right-angles...Honestly, I think the whole game should use a GamePad.. I think I would actually buy this game. But of course that would probably change almost all the level design..
