There isn't a lot of content (v0.0.3 as of writing this review), but the pacing (slow-building romance) is good, the writing is mostly good (some inner dialogue seems overly "girly"), and the 3D models are very attractive. So far, the game is fairly linear, but based on certain insight of the game values when making certain choices, they should affect parts of the story as more content is released.
Also, the daughter completely steals the show in this one so far which I am perfectly fine with. Call it a matter of personal taste, but there's nothing hotter to me than getting a naive and young blossoming woman to fall for you as you help her grow into herself more by letting her become dependent on you.
If you're a fan of erotica, the way this story currently seems to be headed should allow for a lot of steamy scenarios given that you're dating the mother and have just hired her daughter to be your secretary (as of v0.0.3). The creator also introduced the daughter's more outgoing friend who's also very attractive, so it stands to show that he's also making an effort to expand upon opportunities and encounters beyond the main duo cast of heroines.
I haven't been keeping up with this game since the beginning, so I haven't the slightest idea about the the release schedule, but I am certainly looking forward to future updates.
