Torch can light up and show portion of unaccessible part of the maze
Pitch black section difficult to brute force/navigate --> torches can ease navigaiton by showing the actual path/intersections
Torch might be placed on walls to light up darker section (instead of just lighting up torches already present on the walls)
Player bring the torch with itself after unlocking it; the torch show a small radius in dark area (usually you won't be able to see the player nor the wire in those section --> enforce using torch); Torches on wall when light up have bigger radius than the one you bring with you.
Torch unlock:
find the first light up torch in a secret room (with code to light up other torches on the wall) OR light up torches when sprite touches them (do not tell the player in this case)
