What appears to be on the surface an excuse-plot training game actually turns out to be a rather charming, if short, example of how there's still room for new ideas in the otherwise well-trod training simulator genre.
A very wise woman once told me that "it's never about what it's about," and this game is a perfect example of that. You're not simply training a two-dimensional woman to be a sex-starved slut, you're also evaluating what you, the protagonist, fucked up in order to have your relationship with your wife reach the point it did at the start of the story. Watching the protagonist and his wife both realize they fucked up, and put things back together (with a heaping pile of sex, of course) had me smiling frequently throughout my playthrough.
Gameplay wise, there's nothing new here. You work through a short but reasonably well balanced resource trading style grind, with short vignettes scattered throughout as a reward for reaching milestones. The creator deserves kudos for having it not overstay its welcome, although the pacing of the special events is a little back-loaded. Still, with how short the grind is, this isn't a huge issue.
The art is clean, if somewhat simple. Nothing astounding, but nothing awful, either. The vignette artwork is slightly lower quality than the main game character portraits, but not unforgivably so, and it's all done in the same style so the difference isn't jarring. The clothing and dressing system is well done, and clothing art actually looks like it belongs on the wife rather than clearly being overlaid on top, so points in that department.
So, should you play it? As fap material goes, I wouldn't call it underwhelming... but it's close. However, I found myself smiling at it quite often, and it's genuinely charming. It might not be the best example of an erotic game around from a titillation perspective, but it's an entertaining romp that's worth the half hour or hour it takes to play through.
Strong points: Charming story, polished, well-balanced.
Drawbacks: Short, awkward pacing, less than stellar vignette artwork.
As an aside, I appreciated the relatively low number of typos and grammatical errors. There were a couple - I'll do a replay and drop a note with the developer as to where they are, since I foolishly didn't write them down the first time through - but the count was refreshingly low.
