NOTE FROM THE FUTURE: I'm not going to finish this, so, I'm sharing it. I kinda hate this actually. It's kinda corny and the sprites are ugly (except Flowey- most of the time I like Flowey here because he's supposed to look like this), and it's kinda blurry. The music is cool though, in my opinion, since it syncs with the animation.
