update: halved the resolution for all of my assets, seemed to work. After hours of putting something together a new problem has emerged, now whenever I try to test the game game.exe does not work and I cannot test.
Yes, projects folders are correct. I think it has something to do with adding too many textures or something (though as stated, my file sizes are all relatively small)
It shouldn't be a problem at all in the first place. Try copying your project files manually into a separate folder, name it "Data" and put Game.exe nearby. Then try running it.
