This game plays itself more than an idol game. I know you need to make money Kong, but seriously??? There are way better for money games than this even if you must badge money making games.
After now have playing it. WOW. This is the epitome of what flash games should be. It's simple while being fun, light-hearted, and very enjoyable. Great job!
Also, I understand you want to "cut out abuse" with the trading cost...but to be honest...with a game where production is so little and there's tons of buildings/players to raid. I doubt many people will be using this for abuse. The set up to get to the trading point takes a good amount of time and I find it hard to believe that someone would make another kongregate account just for that. I understand you want to wet your beaks a little, but why not make it 2 fuel instead of the 10 + 10 per stack fuel it is now. Many more people will trade and you will make more money. Win/Win.
How about adding co-op so you can play with another user's survivors and you split the loot later on. For guns and single items you can have a random generator generate two numbers for each player for each item with the player with the higher number getting the item. Also, some higher level missions or bosses to do these co-op missions on would be really cool, because I feel it will eventually get boring and repetitive.
