Error when playing music from loaded png
Hi, @ftsf  ! @felipebueno from the PICO-8 BBS here.

I saw the video where you play Celeste on PicoLove at 60fps and it's preatty neat. So I cloned your repo and tried to run it here but it's throwing an error: `Error: main.lua:1227: attempt to index local 'm' (a nil value)`
