Did you ever want to play Super Mario Bros., but instead of playing as Mario, using Link, Mega Man, or Samus? No? Too bad, because now it’s here!

Play as Mario, Simon, Mega Man, Bill from Contra, Link, or Samus. It’s surprisingly well done, and the characters are even somewhat balanced. Just be sure to use a controller or joypad and map the keyboard buttons, since playing an NES game via keyboard is punishable by death (or at least should be).
This crossover is fantastic! Someone clearly loves retro video games and put some time into this. I’d love to see it ported to an original NES cart for some console play.
