Really well done, nice tightly composed experience. Faithful to the cosmic horror genre by setting up the horror, executing it in a way that's internally consistent with its own logic, and leaving you to sit there stewing in the fact that while the fear you just felt makes sense, the THINGS you just saw don't make sense, and never will: such is the 'cosmic' in 'cosmic horror.' The visual and audio context serve as rich dressing for the writing, which is well structured and well paced.
In short, a great case study for showing what a solid cosmic horror game can look like in 15 minutes or less.
