Divis Mortis has an atmospheric setting, nice prose interspersed with gruesome descriptions, and some classic puzzles. I enjoyed playing this game in the evenings over two days. The author's description of the world is darkly colorful, and there are some unique twists to the zombie lore which was a nice touch.
There were a couple of problems however - Some grammatical and spelling mistakes, and a parser problem that made it difficult to use one of the weapons: (Spoiler - click to show)It allows you to FIRE THE GUN (which shoots into space and wastes a bullet), but does not allow you to FIRE THE GUN AT THE ZOMBIE, or even ATTACK ZOMBIE WITH THE GUN. In the end, you have to SHOOT THE ZOMBIE. There was also one puzzle that seemingly required real-world knowledge that I did not possess, and the author did not hint (that I saw) how to solve it: (Spoiler - click to show)Mixing ammonia and bleach creates toxic sulfur vapors.
A solid game for the author's first IF story. Recommended.
