Thank you for this comment. If you ever want to take revenge on your aborted project here are some tips:
• A lot of what happens here is nothing more than experimental, like does the drum beat match the top left 1,2,3,4 bars?
• Tempo is approx. 150 bpm to match with the "blinking" sprites
• This demo helped me a lot to understand how to make music and SFX happen in bitsy
Hope this helps to get more and more bitsy rhythm games in the near future!
