Use flash!!! My level builder engine. Left/right arrow keys to move, and press up to glide up then down. Its different than jumping. It allows you to glide over platforms before sinking, but you must move before you sink. I figured I wanted to make something different than jumping, not that I don't know how to make a sprite jump b/c I do. Click to make a block and flag to restart and clear your level. To save your level: 1) Download and hide the user and the builder 2)right/ctrl clicl the background 3) grab screen region for new costume/sprite 4)select the entire background/everything in your level 5)export your level V.1: Color sensing, glide to jump and sink, normal x movement (no velocity). You can use this as long as you give me credit (co13). Note: You can go through/off platforms. Thats what happens when you use the glide jump.
