I like the mechanics, it's quite fun.

I had troubles reading the blue on black text popping up at the top of the screen, so I have no idea what it was saying.

Also, it wasn't very clear from the very beginning what am I doing there and how. In the first play I got killed without any understanding what just happened. In the second play I figured out that I'm in zero gravity and I need to shoot those red things shooting back at me. After clearing the whole level and flying through the dim purple circle without anything happening, I somehow stumbled up the brighter purple circle, which got me to the next level, where I got killed again. In the third play I tried pressing various buttons and figured out that Q and E rotate you, which was exactly what I needed, but still got killed. The fourth play after noticing the red energy gates I started to think that maybe I need to open them somehow, and maybe the other red things attached to the walls can help me with that. And so on. What I haven't figured out is what do the different green things do.
