Here's a reskin of SMB2 giving the game a Halloween Comedy feel to it. Every graphic is edited and so are all the sprites. This was first shown on Vinesauce back in 2018, the sequel to Super Bone Bros. It should be compatible with level only hacks, hasn't been tested.
But yeah get down with some comedy and bones, whee!
