Super Mario Bros. 3 Mix pays homage to many past and (relative) FUTURE Mario titles, while attempting to remain faithful in spirit to the look and feel of Super Mario Bros. 3.
- All new levels (and a few “remixed” Mario 3 levels somewhere in there)
- Many new songs added from other Mario games (kept some SMB3 classics!)
- Play as Mario, Luigi, or Toad (cosmetic only) in any configuration
- New power-ups (Penguin replaces Frog, Carrot replaces Tanooki)
- Star Coins (which are used to unlock portions of the game!)
- Ability to re-enter past worlds (with level completion intact!)
- Ability to re-enter past levels (to get all of your Star Coins)
- Alternate exits in some levels
- Ability to save progress
- Many new enemies, typically some special ones for the world theme
- All new bosses (many are “remixes” of bosses from other Mario games)
- All kinds of gameplay changes to meet the theme of a level/world!
