I had no problems ran. the game almost a dozen times. Just walked left. watched the debug to see if the music started playing. and no problems with crashing.
However when you want to play earthbound franky. REMOVE THE EVERY TICK condition.
Also as a suggestions.
Make one Ground sprite and use frames instead of a different sprite for every ground block.
Use PLAY not Positional Play for music. Unless of course you want your music to have area effect. However most of time that's not really the case. As an example. walking into a Night Club with a band or music speakers; then you would use positional audio to represent the band having a position and distance.
Didn't you file this first as a BUG report?
