I think this is a great concept and I very much enjoyed it. The music is catchy and appropriate for the game, which helps keep the player focused and prevents them from getting bored.
The gameplay is also very fun. although the timing to move through the gaps is tedious, especially for the segments of the maze where you need to suddenly turn as you move through.
The difficulty is also good. Not too easy, but also not too difficult.
The colours are bright and eyecatching, although I would suggest a background change every now and then. For example, change the background colour every two or five levels.
I DID notice a glitch however. On level 8, if I'm next to the orange orb and I convert the rotation direction to counter-clockwise, I die although the black orb was not even on screen and the gray block was nowhere near me.
Overall, a great game that I would love to see published.
