Couldn't play your game, because I don't have the latest NVIDIA GeForce graphic driver. Please, when you develop a game with the Unreal Engine, that players who don't have the latest state of the art graphic drivers would like to play your game on their computers too. And a game with a size of 5.6 GB is too much!
I only watched your game played on a live stream. Actually it doesn't look bad and the voice cast is good, but please try to make Unreal Games with a smaller size and a compatibility on non-gaming PCs.
