This is one of the strangest games I've ever played and I absolutely loved it.
Other reviews have mentioned the severe difficulty and the need to restart after hours of play and they're entirely correct. This is, at heart, a resource management game with bizarre, unintuitive mechanics and there is zero hand-holding. You will be confused (but also intrigued) from the start of the game to the very end. If you're quick to anger and frustration this may not be the game for you.
If you're patient, however, you'll find one of the most creative and stylized games you'll ever play. The artistic direction is stellar and (though perhaps more style than substance) the atmosphere alone is worth the price of admission.
Be warned that the "story" is vague, dream-like, and never fully fleshed out. Nevertheless, the developers manage to imbue an impressive amount of personality in the characters despite lines of dialogue that are sparse and cryptic as can be.
You should also be aware that there is an excessive amount of nudity in the game. I initially thought this may be a cheap ploy for attention but I'm now quite convinced it was an artistic decision. It contributed surprisingly well to the otherworldly, surreal atmosphere and is never remotely sexualized or graphic. It should be fine for mature players.
Overall, if you're a patient player with an eye for style and an appreciation for some genuine originiality this game is worth every penny.
