I feel like it's either a really early release, or I'm missing something, but it's a game where you pick a pose for her, snap four pics, then buy new clothes and poses, then repeat this forever until you've unlocked everything.

As far as I can tell, that's the whole thing, and none of the clothes or poses change anything, nor do the actual pictures, you could L33T POWERGAMER SPEEDRUNNER STRAT by ignoring everything, snapping 4 identical pics, skipping to the next day, then repeating until you've unlocked everything. I suppose the game's cute, sure, but there's nothing more than the poses and the clothes, which are 90% reskins. Worth a try to play the game, anyway, so long as you view it as a simple toy, or a viewer of some kind and not an actual "game".
