Very nicely done! Your narrative was quite entrancing! And I particularly like the Bioshock references ;)
Some feedback
- I didn't particularly like the walking and backtracking sections, but I guess mainly it was because of the slow speed of the character. If I had some sort of "run" option, then it would have been fine.
- I would have loved to see (or read) more lore of the area, as it was very interesting and had gotten me hooked.
- I'm not too sure of the colour scheme; I would have wanted to have each room a different colour scheme, but that's just me.
Overall, I wanted to explore more and keep on playing! :D
Great job!
