This game has the potential to be awesome! Its a fun game that my kids and I all love but constant nagging to buy $10 (kids version) $20 (girl penguin) plus others and even $ 30 (magic penguin) on top of the constant nagging to pay $$$$ for fish boosts (that you use up) will hurt this game in the long run. I would happily upgrade for .99 and even buy a few options if they were .99 (ie: I have every option available on angry birds and look how popular and successful that game is!)
Developers, getting $1each from 100 people is much easier than getting $100 from one person!!
Parents, be forewarned that you need to make sure in app purchases are turned off if you dont want to be the one paying $100 for a stupid game!!
