I think I mentioned this to you in Discord, but the chilled-out music is a must-have for such a tough game. The best score I could get was 21/50 on normal mode. I think you nailed the limited scope and the cycle theme. Everything feels complete: good control and hit detection, audible feedback, and clear end states are things that a lot of games end up not having due to the time limit.
Overall, one of the standout submissions I've seen so far. :)
Thanks for all the kind words! I'm glad it felt rather polished, aside from the difficulty. I was pleased when I found the music (creative commons music is great!), as I thought it did a good job of preventing me from getting too frustrated while I played.
