I loved the game, but I encountered a couple of things you may want to look at.
7:50 There's an opening in the bottom-right of the room with the movable stones that the camera doesn't follow you into. I didn't fall through the world, or anything, and there seem to be platforms, so I assume it's supposed to be there.
14:50 The glyph didn't activate during the boss fight. The fairy snapped to it, but the animation didn't start. Releasing the button and pressing it again fixed it.
16:25 End screen didn't trigger.
17:35 Game freezes when quitting from main menu.
My specs, if they matter:
AMD 3900X, 64GB RAM, NVidia GTX 1060 6GB graphics card.
Again, the game is absolutely beautiful and plays well, and I hope to play it again when it's complete! Thanks for making it!
