It cool. Move the mouse around for epic effect. On mobile just move your finger on the screen. (Btw in scratches guidelines it says: Scratch welcomes people of all ages, races, ethnicities, religions, abilities, sexual orientations, and gender identities. this means that this project shouldn't be taken down because it has communism in it.)
Thanks for TF2 (Pyro character, Pyro Poster, Demoman Poster) and a HUGE thanks to @TheWordWeaver for making the original project.
