It's uhhhh quite something. The atmosphere is fantastic and genuinely unnerves me a lot of the time, in part due to the low framerate and bizarrely loud footsteps. The areas are interesting but I prefer how Yume Nikki is set up where you know exactly where you're going and there's a lot of things to see and do that aren't random. LSD is more unpredictable but leads to a lot of aimless warping around the same areas over and over again until a random event happens. Time to scour that wiki I suppose.
