uhm let's see some Mario like skills:
enemy bounce: when Mario jumps on an enemy, if it's killed Mario will bounce higher than it's normal jump.
spinning jump 1: spinning jump that goes right foward in curve doing more "landing" damage.
spinning jump2: shoryuken like jump. it will do "more damage" on the punch ( you know, Mario don't hit block using the head, he hits with the fist) but will do no damage on the smash.
pick up/ throw/drop: Mario can interact with objects from scenario like turtles.
run: Mario can run straight foward, if he hits some wall or obstacle the screen will tremble, and maybe reveal some passage or item.
high jump: when running if the player taps "down" then "jump" Mario will leap higher.
long jump: when running if the player jumps will go further than normal.
double jump: when "big", Mario be able to perform an air-jump if he uses the high jump techinique.
wall bounce: when "big", if Mario performs an long jump towards an wall he will be able to bounce from wall to another in sequence.
i hope that's it you wanted.
