Left and right arrow keys to move, space bar to jump. In the editor, drag the objects around to modify the level. Duplicate the sprites to add more platforms, walls, or lava.
A sprite demonstrating the code needed to do basic platforming -- movement and jumping, affected by gravity, and sensing a particular color (black) as the "ground". Uses a Define block with the "Run without rendering" option to handle touching the ground; this avoids the odd "sinking and floating upward" effect that happens normally when reacting to the ground.
