Upon starting the game I was instantly killed by a spider clipping through the walls - it was upside down and crawling? Kinda just flipping all over the place. Anyway - this seemed to occur multiple times while playing, I got killed by something I couldn't react to or couldn't even see. Also frustrating there is no restart so I have to ALT+F4 every time I die, sometimes this is instant.
There is also some extremely weird collision detection occurring, I can force myself through walls, sometimes when I run against a wall my player will "jump" and rotate in a direction uncontrollably. The spiders themselves even seem to fight with this collision issue and walk through walls.
The games controls do not feel good and are sluggish, even being able to control the camera with your mouse would be extremely helpful.
