First I tried porting Pepperman from Pizza Tower but the editor I was using to make the pixel art sucked and it doesn't help that the sprites are convoluted so I just changed the pallet to Pepperman's Pallet from Pizza Tower, It actually took a while, but thanks to WL4Editor and the amazing community we got it to work!
This is a WIP so things may change in the future.
