Story: After the events of Super Mario Adventure 2, Mario and Luigi return home after getting some delicious cake from Princess Peach's castle. They have just moved into a new house so Mario starts unpacking, Luigi starts reading a newspaper. Luigi sees a scam ad in the newspaper telling them how they can “get rich quick.” Mario heads out to see if this scam is real or not.

On his way there, he trips and falls into a deep Cavern and stumbles upon a magical gem, 1 of 12 Gems of Good Game Design. Almost immediately after picking up the gem Mario is sent to Glitch World, and is told by a mysterious figure that he must collect the scattered gems before it’s too late, or else everyone, and everything will become a glitchy mess and the cartridge will get fried.

An adventure awaits! Have fun, don't die! Btw there's 94 exits.
