I don't think I can give a review that expresses more about what's cool about this game than what kumada already wrote.
The one thing I will say to any person considering buying this game, is that although it's playable by two people, it really seems like that would be missing out compared to the fun of playing with 4 or 6, where the dating sim aspect really comes out and you might actually not be sure who goes home with whom! I think it's best played by a group of friends who all feel comfortable getting a little flirtatious (or like a lot flirtatious) with each other.
