Art for @super026anthony HOW TO USE; Click the "Backpack" button. Drag the whole "Thumbnail" sprite into your backpack. Go to your project. Open up your backpack again. Drag the "Thumbnail" sprite from your backpack to the sprite box. When your maze is done, make sure to add a "Stop All" block so the thumbnail comes again. Now, it should work perfectly. If you need anything or it is not working, let me know.
