Hi there! Thanks for reporting - do you mind sharing browser version and os you use? Also if it's not too much to ask for - let me know if any error shows in dev-tools console (ctrl-shift-j in chrome).
Thanks!
Safari 13.1, macOS 10.15.4
Crash when jumping:
TypeError: beepPrepare(freq, t) is not a function. (In 'beepPrepare(freq, t)()', 'beepPrepare(freq, t)' is undefined)
Thank's this helped a lot! Sloppy me, the bug was very silly. Fixed!
