Control Waluigi with WASD, and Dark Cataster with the arrow keys. Jump to launch the ball upwards. I don't think there are any glitches at all
Dark Cataster wasn't created by me: https://scratch.mit.edu/projects/486257924/ It's exactly like real basketball, complete with realistic physics, animations, graphics, and all of your favorite players! Also, just like in real life, there's a 10% chance you die every time you touch the ball. Watch out!
