Ok, I have a clue for you: For the Net-Cubes Worldmap, move the cursor to the center of the screen to orient and then smootly move to change direction.
Alright. I was able to get to the first level. It's awesome! The music, sounds, and feel were nice. I'm not sure if it's a bug, but at least in 1-1 you can't turn the camera, which lead to quite a few deaths. I'm not sure if it's intended, but it does feel a bit unfair, especially because if you get hit once you're dead.
This game has very good potential. Keep it up, and I look forward to playing more!
