Chordosis has to be one of the most moody games I've ever played. Every nook and crany seemed filled to the brim with secrets and unspeakable horrors. I can't recommend it enough and if you like cosmic horror, you should give this one a try, although it's not finished and it has no release date in sight. Unfortunately, my video doesn't make the game justice but seeing that there is also a demo, you can try it for yourself.
