I just took the Sans Moveset project and wiped it clean basically, so you have a nice empty slate to work with. I added some templates for Smash attacks, and made empty template codes for Special attacks, that's right folks, you can't just resprite this.
This contains the BARE MINIMUM. You can make your animations as much more or less detailed as you want! I did a bad job with the hitboxes, trust me, it will work once you change them.
