Nice work! Said most of my comments on stream. Super cute!

The mechanics are there.  The biggest thing for me was the scoring.  I had trouble figuring out exactly when triggered the score.  Did it need to collide the top of the block?  With the line?  Right on the beat?

Timing on these styles of game is always the most challenging part (just my opinion, of course).

I definitely understand the time restraint.  (Truthfully, I'm not satisfied with my entry either.)  But good job for submitting anyways.  You've done a pretty good job with the time given.  Would love to see you keep going with this and push the concept until you ARE happy with it.

The concept is good. The music is also good. The game is just genuinely very nice. I don't like the controls though. It would've been easier if there were 4 consecutive keys as someone else said.

Nice little game. One thing that kept throwing me off was the controls didn't align with what I saw. The correct directions are linked to the correct arrow key, but needing to switch between the up and down keys with the same finger didn't feel natural, and made it a bit difficult. I think 4 consecutive keys would have fixed this (e.g., "ASDF"). Very well could just be an issue for me, though. Regardless, great concept and simple execution, making this a good game over all.
