Nice little project you've got there.
I'd advice turning down the volume a bit. The music is quite a shock to the system when you first turn on the game.
Also, try to make your controls clear WITHIN the game itself, this is advice that I have not followed, in my submission, but it is important to helping people understand your game when you have unusual controls.
One more thing, I am not much of a music fn myself, so I may be wrong, but I think the beats and the blocks are lining up wrong. The 3 beats in quick succession should match up with the 3 blocks, shouldn't they?
Yeah the music is way too loud, a fix instead might be adding a settings tab. Yeah, I ran out of time because of School. I wanted the controls to hover over the spots before the notes fall but.... time. Lastly, yes I believe the middle song is the worst with lining the notes up. I lined them up by hand/trial and error based on fall distance. Appreciate the Comment though its great to get feedback!!
