Super Mario 63 is one of the more complexes, but also more enjoyable modern versions of the game. Not only you must play like always, passing levels and jumping, but also you need to go to places impossible to reach by just jumping. Remember that you can swim, ride the birds to fly, and many other variants that you must find by yourself. Good trip!
Right/left arrow keys to go forward/back, up arrow to jump, down arrow to bend down, and C and Z keys for special tricks.
