Fun mechanic, the limited vision makes for good gameplay. The walking SFX was a bit loud. Also, good design that the spikes decrease your light instead of like just killing you, makes it more interesting.
Cheers for the review man. Funny actually, the light level reducing when getting stabbed by a trap was just me not having time to make a death animation in the last half hour, so I just made it that when the player collided with a trap that the light level went down by one. Limitations breed creativity I guess.
