I dont know if this still applies, but i found a glitch in the old graviter demo where you can jump, then at the top of your jump press Alpha, and it will switch in mid-air. Also, on the 2nd level of the three, if you go right beneath where the enemy is and jump-switch like i described, the door will close while you are in its path and you will be teleported elsewhere on the map. Ill post a screenie later today.

I also figured out how to get back from the other area once you teleport.

Btw, there are two ways to beat level 1, one that is easy, and one that is hard. I think that the hard one is how you are supposed to beat it, because the easy solution does not use the door in the middle.
