This game is, in fact, a nukige (a short collection of erotic stories, no more plot than that). The gameplay is a mix between a visual novel and sliding puzzles, so if you aren’t fond of those, then this game might not be for you. The English translation needs thorough editing: sometimes it was hard to tell what exactly was going on in each scene, but the art is so lovely that makes up for it. Again, provided you like or do not mind sliding puzzles: contrary to what another review on Steam said, they are really easy, so go for it and enjoy the beautiful CGs and gorgeous character art!
