I tweaked the lighting and increased the dark-light intensity. I tested it on different monitor types and it is more than possible to navigate the dungeons and see where you are going while on standard brightness.
I also added tinderboxes to the game. Tinderboxes are collectibles that will give you a randomized amount of flint, steel, and tinder. This should make lighting torches slightly more commonplace.
And now for another short break, more play-testing, email reading, etc.
Good luck playing. Stay sane!
