I have finished it and enjoyed it very much. Outrageous and way, way over the top, which prevents it from being too disturbing. Some of the things the game makes you do are really gross. In a good way.
It starts out like so many horror casuals, in a car on a cold, dark night, but it soon develops into a fascinating and weird experience. Nice puzzles, not all of them easy. If only all casual adventures lite could be this good...
