A terrible attempt at a COYA where there's little choice and even less adventure, the whole thing is a railroaded "experience".
Story: a bunch of succubi want your soul, there's an "angel" that tries to help you for some reason, end of story. Choices with unintuitive outcomes a plenty and the only save feature is accessible on a game over and only goes 20-30 choices back, some of which include the game over event, making it even less.
The porn and models selection is fine, but that's always up to personal taste.
But the worst thing about the game is how much it disrespects your time. Every interaction, every choice, every action and every line comes with delays upon delays. The "game" was originally hosted on some site built around edging and" teasing" and is made with these things in mind, but the end result is a monumentally frustrating experience that's neither fun, engaging or arousing. I am perfectly capable of edging myself without the need to have several second delays between every short line of dialogue.
