BigD is actually my name. When I was tracing my piano I figured Yamaha wouldn't want their name on this thing, so I just changed it to BigD. But I guess I didn't name the piano track, so we may as well call that one BigD as well.
I was planning on adding some other things for the notes and fixing the hitboxes, but I was too lazy. This whole game was very rushed and Unity was a bit more annoying to work with than I expected.
