This is very cute. I like how everyone and everything is doing a little dance in the rhythm of the catchy background music. :D
I played the game on Firefox on Linux, it works without issues. It also works flawlessly on Chromium on Linux. I have no idea how will it run on another OS (I know most people still use Windows for some reason).
The game is very fun to play! Sadly, I am not skillful enough to progress far, so this is as far as I managed (I have an idea how to do it, I just lack the skill to time it right):
