Super Tritan Galaxy is a game that is based off Super Mario Galaxy. In this game, you no longer care for multiple worlds, but rather try and find a rocket ship to crash into the next one. There are also Power-Ups.
TritanTritan is the first playable character. He can throw Building Buds, which are scattered around most of the levels. He doesn't use the Lumas unless he needs them to clear a level.
He does have some special power ups, which Rosalina cannot use.
RosalinaRosalina appears as the second playable character. She uses her magic wand, as well as using Building Buds to create chain links.
Power ups are crucial to beating some levels, while some are completely optional.
