Pretty good. It's hard not to compare to Sexnote, the dev's previous (current?) other project, so I won't even try to avoid it.
Not sure why, but it loses a little something when the obvious pornstar references are a little too on the nose. Animations are smoother and well drawn, the dev's practice has definitely paid off.
It's still early, and I wish the dev would finish one project before starting another, but the content available is pretty good for 0.4, but has a ways to go before getting 5 star.
Also annoyed that Nacho can't be my "tax attorney" but instead is my "tax attorn". Give us a little more wiggle room if you're going to offer that option.
