Usually visual novel h-games are just pump and dump. Just a quick backstory then to the "climax" and done. However, this game (and it's spin-off Eternum, which is still in development), is a huge exception to that. I found myself drawn to the characters, not because they're hot (but it did help), but because of the characters in which you root for in the game. It sets up a backstory, and does bit of character development before you do the sex stuff, eventhough that sounds boring, the intriguing mystery noir plot keeps the game going along with the comedic moments that happens. Caribdis is an amazing story teller, which seems like a rarity nowadays, especially in the visual novel h-game scene!
