High-budget Hunie-Pop like with nice 3d models and animations, with barely any sex.
(reviwer note: DLC mode is NSFW mode)
It looks nice and plays okay, but if you're looking for anything more than suggestive motions and underwear you've got another thing coming. There's clearly a lot of work being put into the animation, it looks great, but the closest thing to a legit sex scene is a main character getting cowgirl'd by his gf (which is a scene entirely cut without the "costume DLC" toggled on), which is unfortunately cesnored so you don't see any good bits). Later on, it's implied she gives you a foot job, and it's implied that you doggy her over her desk, and it's implied she cowgirls you again, all with underwear on. The succubus you two are interrogating blows a thermometer at one point, or chills out in a zero-g pod in her underwear.
There's nothing overly explicit from what I've seen in this game, at least at the moment, which is kind of a bummer considering the polish that's been put in . One story doesn't have any banging at all, spoiler alert, implied or otherwise.
Although, it should be noted that this game is actually trying in the story department. Basically the game is a series of short stories, each involving a girl. Without spoiling, the first is particularly interesting in how it concludes. The second looks nicer, but isn't quite as interesting as the first.
It's okay, but if you're looking to get off, you may find yourself a bit bummed out.
