Stability: I didn't notice any bugs.
Gameplay: Very simple and straight-forward. Keep food bowls filled and doggos "happy". *wink wink, nudge nudge* Not especially challenging but enough to kill five to ten minutes or so.
Aesthetics: Cute, if very basic pixel art. Not very detailed or impressive, but it serves its purpose.
Content (General): Very small and short, as tends to be the case with this dev. Shame they never work on a longer game, or perhaps work a bunch of mini-projects like this into one bigger thing, but ah well. It is exactly what it sets out to be- a very tiny five minute game with some cute pixel porn thrown in.
Content (XXX): A fair variety of sex scenes in this one, for such a tiny/short game, and a decent gallery to unlock once you've racked up the money for it.
Overall: If you like sprite porn, and particularly of the bestiality variety, it's worth checking out. Otherwise you won't get anything out of it. And even if you download it and end up not liking it, you didn't waste much space or time on it, so there is that. I'd probably rate higher if it wasn't so short, but again, that's how these games go. I feel like a 3.5/5 would be a fair rating for this.
