Differences from SMSS
- Unlike Super Mario Silver Spurs, which is mainly in motion picture format, Synchronized Souls is a video game. It is a platformer with some other game types that can be unlocked.
- Major characters from SMSS, like Mario, Sonic the Hedgehog, and Gumball Watterson, do not appear in Synchronized Souls.
The story takes place in a new universe, the Synchroniverse.
Mandark, irritated after losing to Dexter again, researches dream psychology and comes to a conclusion that dreams connect you to your alternate universe selves. He steals the blueprint to Dexter's Dream Machine and designs his own variation of it. This new device is built specifically to allow Mandark to take control of his other selves.
Dexter, quick to realize this as usual, upgrades his own Dream Machine, and must teleport between dimensions to gather up heroes to help him stop Mandark.
