Version v0.04B.c review (as a quick aside, the paid version is on .06B so I don't know if any of my criticisms have already been addressed in the newest version).
I liked this a lot. The gameplay is fun and feels well thought out. The girls are pretty cute. Money is a little weird: you need to earn $1500/month for rent but you can do that in like a day. Everything else (card packs, gifts, and clothes) are super expensive so you'll play the card game A LOT. The games go quick though and I rarely had any difficulty winning on the second hardest mode so it never felt too tedious. It is kind of crazy, though, that the game goes up to level 100 and after two hours I'm level 6. Not sure what the dev's intent is there.
My biggest criticism is with gifts. Those are the only way to raise relationship with the various ladies. You can't give the same gift twice but there's nothing (that I'm aware of) indicating what gifts you have and haven't given. With relationships going as high as 20 in the current version, you basically need a spreadsheet. Also, each girl likes one type of gift and some are obvious (the controller probably goes to the gamer) but others are like a skirt or a box of donuts and it would be nice if they just had the traits shown.
Overall though, I thought the card game was well thought out and the girls are cute and this is a fun little game.
