Super Smashin Scratch is an idea invented by LedPencil. It has been liked by many scratchers including schoman3. However, it is considered a "lost" project because LedPencil indicated that he is not going to complete it. However, platformer designer, 211A has agreed to finish it and is expected to share it in 2017.
The individual projects are complicated and require careful combination, which might indicate why this project will not be viewable until 2017.
