I am a bit confused because I played for 10 minutes and I was completely lost and then I found a locked vault. Then the bad guy appeared, asked me a question. I choose randomly and got hurt. And then he just continued to follow me, without doing anything. I also found pages indicating directions but telling "go right" when you don't know from where the player will come is not really helping...
Otherwise the game looks great, I love the post process you added! The sound is nice too, even tho I would have liked to have a background music when exploring all those empty dark corridors.
Good job for posting the game anyways :)
