Arrow keys or WASD to move. @Coltroc for the platformer code. I modified it. I made this remix when the original project was a 5 minute game, @Coltroc later spent 5 more minutes working on it, adding new levels and making it into a 10 minute game. His ceiling-sticking mechanic is different from mine, since he added it after I remixed. You can see his video on it in the description of the original project. He also has another video on his channel about it. https://api.scratch.mit.edu/users/tobot8000/projects/639855682
