Congrats on the submission and participating in the jam.
Like others had mentioned, I had trouble accessing this with a Screen Reader, so I definitely think if you hadn't before, test your game with NVDA or VoiceOver to validate that players can get to the game.
I thought the clapping was definitely an intuitive way to line myself up with the pins, but were a little too constant or frequent, and along with the new pins, made it hard to keep up or feel like I could make real progression. I think you could very easily turn this into a fun game of rounds where more and more pins show up, after already successfully knocking some down. Alternatively, putting a timer on it and seeing how many pins you can knock down in a specific amount of time is one option (although that is definitely the more stressful route 😅).
