I can hear it, but no promises. And no OCs.
Team Mario: Mario, Luigi and Wario
Shared moves: -Jump: Acts like how jumps work in Mario games.
-Roll boost: Taken from Super Mario Odyssey, pressing down+A will, well, boost their rolling.
-Ground pound: Pressing down mid-air will accerate them downwards.
-Swim: Pressing jump underwater will make them swin like in 2D Mario games, though they should still drown
Spin jump (Mario): Performed by pressing B, from the ground it acts like a higher jump, from mid-air it gives Mario a tiny upward boost like in Super Mario Galaxy.
Green missile (Luigi): Holding up+B Luigi will charge his "green missile" move. The longer you hold the button, the faster it goes when you release it.
Shoulder bash (Wario): By pressing B while running, Wario accelerates to a speed faster than he usually goes, breaking everything in front of him.
Here are Mario and Luigi's spritesheets:
And here are the two games I got some of the moves from, you may need to rip the sprites from there too since the games were made after the sheets so some moves are not included in the spritesheet: http://info.sonicretro.org/Somari_the_Adventurer https://forums.sonicretro.org/index.php?threads/luigi-in-sonic-1.39248/
Sorry If you see this as a spam, but I had to split this into parts since the messaging system can't handle so much.
