Theme: Kind of spooky, but the effect was muddled by lack of ghost animations and camera clipping issues.
Fun: Find and bring items while being chased is a good core mechanic. The sprint should be more noticeable, and you should be able to outpace the ghosts or have some other means of escape. Ghosts having colliders and bodyblocking you from leaving rooms and/or ramming you into corners for a quick restart wasn't too fun. Having some way to scare the spooks away or being able to tell that they are coming with sufficient time to hide could also help
Game Design: Overall, a good idea that has some performance and gameplay issues. There are probably too many dynamic light sources in the game scene, as the menu scene (level select) works like a charm. You should remove colliders from some objects that you can pick up, as dropping them and stepping on them can launch you. The camera clipping could be an issue with the near clipping plane (I don't know UE that well to tell), but it deffinetly hinders the experience near walls or the ceiling. I also had a problem between the "use" and "pick up" keys (at first I was confused why I couldn't get the flashlight) - try and have as few controls and possible, merge some if neccessary.
Regardless, this is a very presentable game and after a few fixes I'd love to revisit it and play it through.
