Lighting is very moody, but perhaps too dark because it made it difficult to see. Perhaps the player should have a light source? Also the torches are casting a big shadow where they probably shouldn't be.
Nice inventory system. Ambience isn't too loud, but it would be nice to have a volume slider. The highlight effect on the switches is good.
Combat is good, it responds properly and gives good player feedback. The variety of weapons is impressive, and I quite like the style, however the sword can clip through walls and when you turn with the sword the animation bugs (but I'm sure with more polish it'd be great).
