Did you try right click?
Yeah, I tried both clicks and a bunch of random keys. Not sure why it didn't work. It was a fresh install of Chrome on Windows 10, so pretty standard platform.
Did you have any item on your hand or something?
not that I know of. It was really weird, I could do everything but actions. Teleport, breathe, etc. It was all fine. I might try it again later. Regardless, I still got a kick out of the game because the breathing mechanic was so funny.
I tried using Chrome and the game works fine. Odd.
