I really enjoyed the exploration aspect of the game. However, the shadow occludes so much of the playable area, which really makes the "combat" frustrating. I had presumably cleared out a section of the map, so I went to kill a scorpion with the gun I just found, and ended up walking right into it because the shadow made it hard to see even an enemy that I knew where it was because I had passed it before. Then I killed it and started walking back to an area I knew was clear, only to find an enemy spawned there, and it killed me. The thing is, occluding most of the screen with shadow and action-style combat are very hard to blend together properly. If this game focused more on the exploration, the shadow could've been a much better difficult mechanic.
