Yes! I'm alive! :D
Great story and atmosphere. I recently visited the Brussels sewer museum, and strangely enough, it reminded me of it (it was very interesting! with a slightly claustrophobic and spooky atmosphere). The little puzzles were within my grasp, and I obviously made the right choice to survive ahah. I didn't encounter any bugs. I'll try again if I have time, to see the other ending(s?). Well done!
