Use the arrow keys or space bar. Q: Do we have to remix the project? A: Nope! You can just link it to me if you want!
The song is the music box version of Tonari no Totoro from My Neighbour Totoro. I think I covered everything in the project, but you can ask me questions in the comment if you're confused! This finishes on May 1st or when I get 20 entries, although I may choose to change that. Good luck!
