In Courier of the Crypt, you'll play a young courier who must, well, deliver a letter to the keeper of the crypts. Unfortunately for you, this will entail going into said crypts in order to meet your goal. Obviously, this is rather dangerous. What makes things worse is the fact that your only mode of defense is a magical torch. If it gets extinguished, you'll be rendered helpless. According to the TIGsource devlog, there'll be a fair amount of puzzles to solve and treasures to gather.

If this sounds like your sort of game, you can keep tabs on its development over here.
