It feels a bit like a WarioWare styled microgame, just at a slower pace. Not a problem, as it seems to match the vibe of the game, but I feel like referees are usually in higher paced environments.
I love how you leveraged emoji to get everything across. For the interface, I feel that the prompts (like for music, instructions, and click to start) should be buttons instead of just text. It’s not very clear how to use them, especially in the case of click to start being a button and not a “click anywhere on screen” type of deal.
