I used Unity for the game and Krita for the art.
Thank you!
Edit: I added the above info to the page just now, and am mentioning this here so others would not think it was strange for you to ask.
ahhh I always wanted to make rhythm game but have no idea how to do it in unity
I followed the tutorial series by "gamesplusjames" on Youtube. This was my first rhythm-based game, but not my first-ever game.
