This pack includes:
- Edited graphics to fix palettes and changes sprites to be more "smb-y."
- Custom enemies with slightly edited graphics to fix palettes
- music
- the tileset
- backgrounds for laying out the BG tiles
- and a CREDITS.txt
If you want to improve anything else in this pack (such as more custom enemies (as this pack has very few), just make sure they follow the correct palettes), then once again you're free to do so.
