Nice game, terrifying experience but i think is made in unreal and that's why the game have a bad performance in my pc.
But the game is a very nice experience, but after kill the monster in the room with the balcony, I had no idea where to go.
Yes, the game is made in UE5 and due to the lighting it will probably struggle on some PCs.
When you get to the room with the balcony, you jump up onto the chair, and then jump up onto the balcony rail. When you're on the balcony rail, platform across all the other balconies until you reach a ladder. Hope this helped :)
