Thank you so much for playing my game. I did have problems with the level design. I was planning on adding tiles that reverse gravity, and switches that change the colour of walls, but I didn't have time.
Some web browsers do have problems with pico 8 sound.
After the jam is over I am planning on fixing up some of the problems, and add stuff that I couldn't do, due to time.
As to using the wrong two, that too has been fixed.
