I dig the art and story, this game has a ton of personality. Cute characters!
One point of friction is during the rhythm game, I dunno maybe this is just me being so used to Guitar Hero, I expect the four frets to be arranged on the bottom of the screen horizontally, so that the four frets correspond to V B N M in my mind. I'd like the frets to light up when I press V/B/N/M. Also I'd like the falling notes to fall a bit slower, I was never very good at these rhythm games!
Honestly this is a good itch.io page, you've checked a lot of the boxes - but can you clarify, what's the name of the game? And what's the name of your game studio? Is the game called Sardine Studio? The game title should be in the top banner.
