The normal controls for Mario and Luigi: Partners in time, but without the babies.
This gameplay is totally original. You can enter worlds like Snow Palace or Water Splash. You can find secret rooms by pushing buttons that will open up chunks of wall, thus revealing the secret rooms. Fight demons with the magic crystals.
I'm sorry, but this comes later.
Fight demons, solve puzzles, and get power-ups in this mode!
I'll write more later.
