Really like how this game is about both literally and metaphorically diving deeper.
Unfortunately I encountered a bug where full screening the game after it starts breaks it and essentially forces you to reset, so I wasn't able to finish it.
Hmm ok, i tried it a few times now. In Chrome seems no problem at all. In Firefox i saw something similar what you describe, but game seems to continue when you click with the mouse on the screen. Is that the same one you meant?
Definitely shouldn't happen, i'll check out, thank you for reporting it :-)
