- Outstanding puzzle concept that plays with space in an awesome way.
- 2D levels are great at easing you into the core mechanic.
- I am mixed overall on adding 3D after so many levels of 2D. It feels like a whole new game was added which feels a bit jarring, but maybe it's me. I recommend you utilize slightly simpler 3D earlier on as foreshadowing to rotation. Maybe add levels where preset rotation only occurs when you hit a switch?
- 3D intro levels could start off a bit more simple, with more easy levels added afterwards.
- For the UX, the interface mostly works, but there's a bit too much particle fx in the glitches and compression. They were very distracting and made it tough to concentrate on the puzzle at times.
- Overall, fantastic stuff that will only get better with iterations.
