Unless you set up a settings screen yourself, Unreal decides which graphics to run the game automatically depending on your hardware. Let's just say it doesn't work well when you use the latest stuff like Lumen/Nanite. Not many assets in scene as well. I enabled raytracing as well for supported systems, maybe thats why you had performance issues. You are right, it's too brief even to be called a concept. It's going to be a game where you will sit on edge both in 2D and 3D world, there won't be a fade-in/out of the 2D game. In any case, thank you so much for playing it!
