Hello smartcodegames, I guess this is the only way I can reach out to you to help you patch up this glitch?
Here's the glitch: At ANY level, 1. Click on a movable object to move it 2. Don't click on it to place it down yet 3. Press R 4. You have two of the same object now.
This is a really big hole cause you can use this to complete many levels easily.
