Double-click flag so that the music syncs! Sorry if it's not as good as my other projects, Christmas is a busy time for my family. I will update this when I get the time. Updates will include: Backgrounds, EXE phases, Better sprite positioning, health bar, and whatever else I can think of.
@SquigglyTuff for AYS, @Undertale_fan10101 for the tails sprites, I animated the metal sprites myself, and fukipidia for the rest of the sprites.
