# This is modified from Melody Maker by SuperRiley64;
# all that's really changed is the note frequencies
# and default melody.

# To do: Change the title screen,
# maybe add a credits screen to save room.
# Maybe make an expanded melody maker game that has
# multiple different scale options, if I can figure that out.
