Videos like these are always satisfying to watch and make ( ᐛ )

The Magic:

• Export your stages of progress as images.
• Paste to a new canvas (don't merge the layers together).
• Bind a shortcut key to "Delete Layer".
• You can use an eraser but I like using Transparent Color.
• Erase the top/first layer.
• Delete the layer.
• Repeat until the last one appears!
