Nice visuals and audio :) The controls didn't want to work for me at all in fullscreen, but worked (I think) when framed inside a webpage. I think I got stuck when trying to get out if I was supposed to control the direction of flying when getting out, tried 3 times and each time no control over the movement, only once I managed to fly out of the hole in the ceiling, 2 times just kept bouncing up and down indefinitely (and loosing all my collected gems with each hit). About lack of rumble in web exports, I think it's a known Godot limitation for a moment https://github.com/godotengine/godot/issues/96985 or at least was? The keyboard mapping for escape and enter keys in browser, and arrows instead of WASD was... interesting choice ;)
