Man this game is wildly unique, I loved every moment of it! The polish here is amazing and while I started expecting to really get frustrated by the controls the tutorial really eases things in nicely and before I knew it I was gliding through the world without a single thought about it! The sound design is also just superb, the music was beautifully calming which really really helped for some of the more demanding puzzles :)
The only thing I can suggest is trying to make the buttons stand out more from the background, there were a few moments where I just didn't notice them or my brain just blended them into the background a bit too well
Awesome entry!
