I like the concept, and the terrain reveal feels good. It does nearly feel like picking up an ingredient is a penalty, as you'll effectively lose your sight, or lose your special bullets.
And I got randomly stuck on nothing 2 or 3 times while strafing backwards (knowing I wasn't up against the wall)
All in all, very compelling game with great promise. Just some kinks to work out; like maybe putting special bullets on a different keybind so you don't lose your sight.
