The idea is wonderful, and so is the execution. If someone doesn’t like the genre, that’s okay, it’s a matter of taste. Of the minuses, there are only a dozen grammatical errors in the translation (Thank you that it exists, and especially full-fledged) for the entire rather large game. The lack of multiplayer is not a minus, since there is no need for it. Final score: 9/10, 1 deducted for translation, and even then I’m being very picky. There's nothing else to shoot for.
