Press Play to start the song. (Only has Hot Cross Buns) Arrow Keys for the designated blocks.
This is more of a proof of concept than anything else. I would like to continue working on this. Possibly add more songs or a menu. Chords are possible, though I didn't include them here. Feel free to remix this project to make your own songs. The lists are straightforward enough that I think you should be able to make your own songs. The "tempo" variable controls the time in between notes, and the "speed" variable controls the downward movement of blocks. 1 = note. 0 = rest.
