Jumper EngineThis is a platforming engine with wall jumping, skid jumping and double jumping. You could use it to create a Jumper fan game with Ogmo (or your own character).
The first level.
The second level: with gray, green, white, teal, purple and yellow stars. Respectively: no double jump, infinite jumps, invincibility, no wall jump, reverse and 'return to normal'.
Last level level: all doors.
