Just started playing this yesterday, and it seems enjoyable enough so far as casuals go. I just used up my last free picture slot, and don't have many gems saved up, so I imagine it's about to get more frustrating. Really, the main point of these games is content, and I'm F2P. If it's too hard to unlock pictures, I'm sure most of us will move on until they make it easier (Honey Crush smartly halved the cost of their pictures early on, and those were even easier to unlock than these).

Personally, not a huge fan of the girls/art. A couple of them are cute, but they're drawn a bit like pre-retouched Fake Lay girls. I may be spoiled by the work done by Booty Calls and Fap CEO. I guess the good news is that makes the lack of picture space a little less torturous.
