Cool to see a rhythm game. I didn't realize at first that Burst enabled the multiplier, and had a double take with the controls, but the game has good flow once I figured it out. One suggestion might be to make the Burst bar fill and deplete faster to encourage players to play more precisely (Burst fills faster if you hit wood blocks perfectly on beat, and metal blocks deplete a lot), allowing players to get more Burst time if they're playing well. This game is fun, good job!
