Please people. Stop blaming games for your own faults. Almost all kongregate games save to your cache. Don’t clear it and disable programs like CCleaner as they will wipe your saves as well. Also look at your browser settings to make sure your cache is large enough and doesn’t get emptied periodically.
@nephelhim. Play the game first. You'll soon see how you hundreds of explorers are usefull and how 30 in tribute will get you nowhere. A market system is really not necessary. All resources get used in higher and higher quantities. Don't judge this game before you have reached zone 80 or higher. It's really well thought out.
@Lilpaladin, Grandpa clicks can net you extra purple coins. Supply crates give you 100, explosion and awesome crates can also give you some. There is an ascension power which helps and possibly the mystery effect from your pet gives them. Not to mention progress bar modules. There really is little grind in this game. Only choice between which resource to focus on.
Small detail concerning higher level block. I now have 79 gyms providing a total of 474 block. The next one costs 266M. A level V shield gives 1877 block each. And that quite cheap. My 12th costs 410M. You might want to add a few more upgrades to gyms to make them more effective in comparison.
