I don't know what that means.
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?
a credits.txt file is fine if you don't have the time to make in game credits. It's a jam game after all, so there is some leeway on crediting. As long as you do it.
I really don't know what you mean about a laggy full screen game. But of course the game can be full screen and you can use any style you like as long as it's an adventure game. So what you're talking about is probably fine.
