Really enjoyed this one! It took me a minute to figure out what the things in my hands were, and that the box chasing me was dangerous, but it was a lot of fun! I did run into a bug of some variety - on the 3rd or 4th puzzle (the one with 3 switches all in a square area) the game got really stuttery, then froze up completely. So I didn't get all the way to the end, but the art and soundtrack were both beautiful!
Also, one Godot dev to another, whenever you're aiming for web builds it's a good idea to have a second non-escape key assigned as Pause, as in any web builds Esc will either release mouse control or exit fullscreen. I've started just always binding a Pause input to both Escape and "P" for good measure.
