It is a very cozy game, I love the background art. I would have liked to see a bit more in terms of the UI, maybe a score counter and a level selector.

As a cozy game made in 3 days, it runs and is certainly cozy! I like how the leaves rotates to the arrows that you need to press, and the art style is very cozy!

As a rhythm game, pressing the buttons to the music is a core mechanic, so the bug where they don't line up is frustratingly gamebreaking. All the parts are there, I hope you can figure out a fix for the bug!

This is the first rythm game I have seen in this gamejam so far! I liked  the background art I'm guessing you made it yourself (didn't saw it in the credits) great work.

Adding some simple feedback when pressing notes would have improved the overall enjoyment and feel of the game a lot.

Nice job on your third ever game :)

The game really needed some effects on hit and at least some basic scoring. 

Also, your bug might be tied to the fact that you seem to autostart the music and the timing might get wrong depending on how much time it took the browser to do so. Manually running the song on player pressing the first button might fix this.
