Hi! Thanks for participating in this jam!
I guess that you have some sort of sound lag since it will occasionally stop playing.
Hi! If you're talking about consecutive jumps not making any sound, that was intentional because when I set it to make a sound every time, it gets really annoying at the level 4 and 7s tighter 2 block areas, it makes a very loud noise there, so I made it silent until you release the space bar and press it again.
