Thank you! I'm happy someone liked my silly ending 😄
In the first level, did you hold your mouse down to make small adjustments while it was playing? I made it such that it only advances if you don't touch anything for the entire bar in case you slip the panel away the very last second. Though later on I made it such that the panels would align themselves after the level was cleared, so now that I think about it that safety check doesn't make sense anymore and I should remove it.
The camera controls could definitely be made easier to use. The current controls were meant to handle 3D levels where you can translate and rotate in more than 2 axes, but it turns out the levels become wayyy too hard with that many degrees of freedom 😅
I love rhythm games! I haven't played Parappa, though my song is inspired by Rhythm Heaven (DS). Specifically the ""Built to Scale" level. It might be subtle, but there's a part in my song that has the same beat as a section from that level!
