Any key (that Scratch will recognize) will reverse the direction of gravity. You can choose from three different costumes for the gravity ball and toggle effects using the sliders. The effects are really laggy and aren't complete. I'd recommend not using them. Once you find a preferable setup, feel free to hide the sliders. Speed changers and size-altering portals will come up at random.
All credit for the graphic and game design go to Robtop games, who created Geometry Dash. Also, thanks to Griffpatch for some of the scripting ideas in here, such as the hitboxing and the scrolling system!
