Great, but a tiny bug...
This is a pretty good game, however, I found a little bug. You can only play one song each session of the window... trying to play two songs without closing/re-opening the window seems to have made all the orbs disappear. Also, mouse mode was sort of easy, because you just had to repeatedly do a certain thing, and you would catch all the orbs.
9/10, 5/5 (I round up.)
