Even though SmileBASIC has the power of a SNES, there really aren't any platformers. Even the games on here that are considered platformers don't have a jump. Does anyone know of any good platformers with jumping?
There is "Save Christmas" made by Nathaniel, but you'll have to ask him for the key.
Also, another warning, it is made for the New 3DS so it doesn't run well on the old 3DS. Look on SBS (Smilebasicsource) for other platformers.
That's simply because programming jump physics isn't easy. There is also a little platformer made by 12me21, it's pretty good and has good jump physics. You play as a green block.
