This Roto Disc edit follows a pendulum trajectory. It was originally part of a pendulum-based sprite pack by Alcaro.
Now SA-1 hybrid.
(Rykon-V73): Added a .json file for the old version of the sprite and added a .json file for the good version of the sprite. There are 2 ExGFX files for the sprite. I do suggest using the good one, since it has the 2 firebar GFX removed. You can go back to the old version though. Read the readme for details.
