I remixed this project! It now has:48 buttons!
It even has a DIY mode for those who want to do the dirty work themselves(Doesn't work online)! Click on Sonic to heal him, and press 2 to alter certain buttons.
Here's some awesome combos:
Cat+Mario+Elmo+Warrior Cats=Teamwork Power!
Balloon+Mario+Plant=Mario hates plants.
Shark+Shoop=A Shoopin' Shark.
Epic+Punch=Wipe that grin off your face!
Mario+Bowser=Final Boss Battle
Kudos to the original creator.
