You should see how much graph paper was used to try and beat this game...
This was tough, but I persisted and persisted and persisted.
And then I gave up, set player.illuminated = 9000 i.e, gave myself a lot of candlelight and kept the enemy at bay, put on "I'm Not Afraid" by Eminem, and only then managed to complete the puzzles as needed.
Well done keeping me engaged to a very serious level.
Great graphics, great idea, nice puzzles.
