It's my favorite rhythm game. You did a great job. The selection of songs and the design of notes are very interesting. The inspiration of Octopus Burn as a note is really great. However, I had some doubts at the beginning. I don't know when to press the button. It was only after several rounds that I found that the bottom row was the standard for judging the timing. My suggestion is to add some changes in the background and highlight the place where the notes catch.
