Sorry 😂
No, I mean like when I package a UE4 game, when you run it, the game will be a full screen window game. You know what I mean? And then it lags a little (like my Project Parkour game). It won't slow down your computer, I don't think.
Also sidenote here, I am going to be making assets for my game, especially modifying some assets from the web. I'll also make a credits txt file, is that fine?
