Very cool idea, I like the mechanics and the control. I found the game a bit too difficult, some bullets were incredibly fast for me to dodge without memorizing the patterns, and I wish we could take a few hits before dying - because I really wanted to get through the entire song but I got a bit stuck on the triangle spiral (but tbh that was a super cool pattern, I just wasn't able to do it haha).
Overall very interesting game. Great job!
