Thanks for the feedback! Great to know that firefox (maybe?) works. It didn't work when we tried it after uploading and we had similar experiences with firefox and Unity WebGL games in the past.
Yeah, I wish we had a little more time to work on the level design. Our game/level designer couldn't join this jam due to internet issues, so it was a difficult balance between gameplay, level design and polish in those 48 hours. Didn't help that it took us over 5 hours to come up with the idea haha.
