I didn't got what happened but I liked the game. Love how it looks actually. Controls are nice, and coughing sound that happens sometimes when you kill an enemy made me laugh, want to hear it more and more haha. And "Mortis" sounds cool. I also think voice acting is good.
What I didn't like is that you are forced to listen to the first dialogue before starting the game every time, it is really frustrating. And not only last room is unfair, the enemies can run from it to the previous room when you are about to enter.
Overall, not counting that blocker at the beginning, I loved it, wish it had more levels (and more fair)
