I tried to play it and got the same black screen that picklejarpotatoes (great name btw) got. I'm on windows so it might be an issue with the game.

I unfortunately did figure out what happened. The intro vid wasn't included in my packaging so the game couldn't get past it on other peoples computers but could on mine because it could still access the file. I have fixed it and only it. I had no idea Unreal only allowed specific naming for video folders, it HAS to be Movies. Very dumb.
