Had a lot of trouble trying to move around and pickup stuff. I think I got killed by the zombie before I even got to load up my weapon. Therefore, I didn't really get to play it but I would say visually you should try and keep the assets you use relatively close in style to tie everything together better. Low poly style vs those high poly zombies don't really gel well together. I'm glad I got to play an unreal VR game, there aren't enough of them!
