Hello there! Great to see other games made on Unreal Engine! 

Unfortunately, I can't say much about the game and how it feels. It pretends to an intriguing story to tell, quite interesting, but then the protagonist enters the cabin with literally zero visibility. You need to work harder with lighting inside, maybe some post-processing or emissive color in Material properties. I just had to quit the game after 10 minutes of wandering with 100% black screen in my viewport. That doesn't feel good. No offence.

Some notes about Player Character. Looks like the Skeletal Mesh is misaligned from the Actor's center. It is noticeable when you try to rotate the camera in Third Person view (in area outside the cabin) - the Character if floating around the center instead of being rotated in the center. Also, there is no animation of turning around. Dodge action ([Q] and [E]) also has no animation. For some reason, there is a camera jitter if try to Crouch repeatedly. If the position of camera is adjusted by Timeline, you should change the logic to call [Stop] first, then [Play] or [Reverse] but not from Start/End.

Lastly, sometimes the Character's Mesh can overlap the viewport and be partially visible. Therefore, the First Person camera (which is attached to the Player Character) needs to be moved forward a little bit. 

That is all I would like to advice for improvements. Keep Up the Great Work! 

Wow, this looks like AAA title :)
