As someone who plays around with Rubiks Cubes a lot. I can say I really enjoyed this game.
Of course it would have been even cooler if it was possible to turn the Cube around, but as you play through the levels you also get used to the overview on the UI.
Sometimes I didn't understand when I can move the Player between the Cubes and when not. Would have been cool if those Blockages would also show up on the UI, so you can plan your Route better.
Music and Visuals are great! It has a really good vibe.
