Mushroom Kingdom Fusion

Mushroom Kingdom Fusion is a platformer that fuses traditional Mario-series gaming with...pretty much every video game franchise under the sun, it seems. Bowser kidnaps Peach (again), so Mario and Luigi set out to rescue her (again)...except this time, Bowser actually had a pretty decent reason to kidnap her.

Cue a huge adventure with a ton of playable characters using a variety of play styles, filled with awesome music, level/graphic designs, and a great dose of nostalgic levels – a combination which is nothing short of freaking awesome. All this, and it's only just over halfway finished (0.53).

It also has a sister game in development, Super Mario Fusion Revival (up to 0.41), which sticks far more closely to traditional Mario goodness.

Extra World Map?


(Note that this map was spliced together from two screenshots, hence the duplicated UI.)

This additional map can be found by using the "Next Room" debug cheat on the World 9 map. It plays no music, the background is an animated static effect that does not scroll, and none of the levels can be entered or even display names. On top of that, the pipe to World 1 leads here:



That's the player (Spartan Mario, in this case) on the island in the top-left corner. You can't move anywhere, even in debug mode.

Vinny


"Vinny" was a debug character in early versions of the game. He was a copy of Mario with unique sprites that was invincible and essentially locked into a Tanooki Suit mode with infinite flight. He was removed at some point, but his sprites (at least) remain even in the current (v0.53) version.

He only has small and big sprites, with no other powerups.

Unused Simon Stuff


These overworld and pickup sprites seem to reference an unused form based on Knight Man. No other remnants exist.

Misc. Character Oddities
Luigi has a duplicate (J) of his Fire Luigi sprite folder (B) with black lines for the eyes instead of the blue-and-white eyes in the used version.

Wario has duplicates of all his sprite folders (labeled WA, WB, etc.) and lives icons for Waluigi. Though the duplicate sprites are currently identical to the used versions, the lives icons indicate that they will be used for Waluigi when he is added.

Link has sprites for a form wearing the Keaton Mask from The Legend of Zelda: Ocarina of Time and Majora's Mask. It isn't used, and unlike the other folders that are labeled by letters, the folder is simply called Keaton. It also has spinjump sprites from Mario in the folder, for some reason.
