I have several Kairosoft games and really enjoy them. This game, however is frustrating because the features are buggy: first, the game will only play in portrait on my iPad so the fishing controls dont work right. Second, when research completes for a new card, they sometimes dont appear in the card list. Third, the game is very laggy. I have many games on my iPad and none of them are laggy. I hate the Specialization feature because it forces you to spend money on things that are pretty much useless. And they keep escalating in price and sucking your money up for little or no return. For example, I had to pay $1000 for a return of $10.
If you say no to them, they just stay there and, you are forced to pay. It would be nice if they would go away if you click no.
I would wait to buy this game until it gets fixed.
