just press any key to start. it will go repeatedly if you press s/down arrow at the end and if you wanna go back just press w/up arrow (no mobile support i think). If the orbit line looks bad is because I couldn't use a mouse.
credit goes to me and only me cause I'm the only one who actually worked on it. (for making this presentation). I will not work on this ever again when its finished cause its a school project. I might even delete it
