Did not have time for music or ambience sadly. barely managed to finish it in a playable state.
When did the game crash? Did you play it in browser or downloaded it?
I have just figured out what makes it crash. Its because the browser closes a tab when ctrl + w is pressed. I didn't know this was a thing. The fix is to play in fullscreen mode via options or pressing w before ctrl. I have added this into the game description now.
Yeah I really wanted to add music, but I tought better none than something rushed that sounds bad or doesn't fit at all.
