Presentation is pretty nice. The sound fidelity is pretty good. I found the music loop to get tiring pretty quickly. Would have been nice to have some more subtle music. I think the amount of text in the game could be off-putting to a lot of people. It would be nice to have more game-integrated visual guidance for how to solve the puzzles. If you skip the text you kind of have no clue what's going on aside from opening up the menu to look at more text in the hints.
The movement controller would benefit a lot from having some aerial drag you you don't move laterally as quickly when you're in the air. The movement sensitivity for air time feels too high.
Nice start.
