whats really great about the game is after you have done a trade in the market area if you keep save all the time you can gain Experience points nonstop!
I like this game but instead of useing kongregate creds to do certain missions I would think that exchanging mission creds for fortune creds would be better.
I loved the game FlyAnvil. I would suggest for the next one allowing for survivers to be alowed in the game by finding them with your characture. Mabye even allowing the survivers to protect the base from zombie attacks while you use the tower, or allowing them to come on missions with you to find other survivers and take control of the areas from the zombies. Besides that I really loved what you did with the game and everything. Hope to see a number two real soon.
