Small animation I made. The original idea was just a bouncing ball hitting an edge and bouncing offscreen, but I didn't want the ball to pop out of nowhere, so I added a pipe for it to come out. Then I added a pipe for the ball to fall into. At that point, I said "You know what? I'll just make this Mario-themed," and turned the line that the ball was bouncing off of into a "?" block and added the dark background. After that, the other "?" block and the brick block, along with the underground floor. Finally, the goomba in the background. What else should I add? Let me know in the comments below.
Sorry I haven't uploaded in a while. I've been very busy.
