Considering this community is very obviously music inclined, I think you guys would appreciate Tadpole Treble:

It's by the creator of the webcomic Brawl in the Family, and it's been in development for awhile now. You dodge the notes of the song as a tiny tadpole and collect items to the rhythm of the song. You should watch the trailer and check it out.
