I really hope that they developers are reading the the comments. The "battle buck" system is way to expensive. I see that I am not the only one that has done the math. I can buy a game off the shelf for $60 but I have to spend at least $200 on this one to unlock just a small part of the game. I am seriously thinking of not coming back because it is so in your face all the time.
Okay, I am going to have to agree with a lot of the comments here. High and low is crazy with almost no benefit! Also, it is way to hard to make any money. I end up getting too frustrated, and fishing gets incredibly boring after a while. Some things on the map cost $100,000....maybe in 2 more years I will get there if I don't shoot myself.
Suggestion for new players: dont overlook the "add peguin upgrade" it is perhaps the most important and cost effective as it adds a fully loaded peguin to your team. You can also wait to release him. This is really effective when there are 120 off screne turtles. Dont waste your money on bombs they hardly get used because you are normally chasing around money. The life boost is a worthy upgrade, but dont use it too soon as your penguins can max out. Finally sometimes it is worth while saving up for an upgrade. My favorite is "body" as it adds a lot of life, and "feet" as it greatly increases speed. To the developer: I really enjoy the game, but a money magnet would be nice, another option would be an upgrade to keep the money alive longer. Also, the last level you dont keep your money. I will even watch the credits again, but can I keep my money?
