If you want a light-weight way to cheat, that does not completely ruin the gameplay, do this:
-) Open your browsers Javascript console (in chrome you can press CTRL-SHIFT-J, use google to find out how to do it in other browsers)
-) Copy the following code:
setTimeout(function() {
game.resources.food.owned = game.resources.food.max;
game.resources.metal.owned = game.resources.metal.max;
game.resources.wood.owned = game.resources.wood.max;
game.resources.fragments.owned = 100000000000;
game.resources.gems.owned = 100000000000;
game.resources.science.owned = 100000000000;
}, 60 * 1000)
-) Press enter
This will give increase your resources (wood, metal, food) to their maximum and give you a lot of gems, fragments and science every 60 seconds.
