It's got an almost comedic effect, how you are just a fish playing song for the Gods... and when you play your note a strange discordant sound plays, lol.
It's like a deep existential game - that doesn't take itself too seriously. I respect it for that.
The simple graphics are nice, very colorful.
My critique is that the game is about hitting the note at the right time, but the game doesn't make it clear when I'm hitting or missing a note. Sometimes the sound doesn't play when I click correctly, so I'm not sure if the game counted it as a correct hit or not.
Also there's no game over state from what I can tell? I can miss the notes and still get to the end without much punishment. Which would be fine, if you are just making a game about getting a good score on each track, but the premise made me think I would get a game over if my score was too low.
A solid entry anyway - the concept makes you giggle and the game offers a good challenge. Good one!
