Firstly, this is a truly unique and interesting setting, especially since it was made in only two weeks, fantastic work by the team! I can sort of see it relating to the theme, but to be honest I found it very hard to play enough of before I had to stop. I got the light and the artefact but it was so oppressively dark that it went beyond atmosphere and into unplayable. From what I could see it looked interesting and ambitious, but yeah I just couldn't see the walls in front of me until I was touching them.
If you update it or do a lighting pass, I would love to see the rest of it, really good job creating something so unique in aesthetic and grand in scale, you could be proud! :)
