Very cool!
I couldn´t complete all the demo cause I got a nasty wrist cramp, but I'm leaving my review with what I played. Collected 3 of the main orbs.
Overall I enjoyed collecting the bullets and how I could use them to progress. Some sections were difficult but manageable once I got the rhythm.
The bullets propelling you upward or backward were an interesting mechanic, but I had a really hard time controlling them. I was using keyboard, and my brain couldn´t quickly connect button inputs for some of the harder challenges (an input example for a challenge I remember being Z-X-DOWN to jump & shoot down, followed by LEFT OR RIGHT and X to shoot yourself backwards, and then another Z-X-DOWN to propel yourself up again, all of this followed by LEFT OR RIGHT inputs to steer yourself mid flight).
Maybe it's easier with a controller. I might try again with it once I get my controller back.
