For a one-week game jam, it's an impressive game that worked well within the time constraint. There are definitely some things to be improved, but that's to be expected for a jam.
Since I play a lot of rhythm games, I had a lot of critique to share, so I found it easier to write a google doc. This also allowed me to include links and images for more clear examples. You may choose to look at it or not.

Thank you for giving my game critique as well!
