If you want to see the bubble-placing code it's in the "clones' sprite, I've placed a few notes in there explaining what the code does right/left arrow keys to move paddle. The game is currently unfinished
I made custom blocks that take clones and let you create a grid of clones, and I decided to make a pong-type game with it. If you want to use it to make a clone-based grid in your game you can use it as long as you give credit :)
