hard, fun, simple
Nice defense game, good variety in enemies, could do with more towers in my opinion. the mine seemed pretty pointless because its churning out 1 Au per second when you castle is doing 6 times that. It is very hard as previously stated, but its do-able if you put some time in it id say. I dont know if this is a bug or not, but when i had around 500 resources, my castle needed 426 resources to repair and i tried to repair but it wouldnt let me.
All in all, a good challenging game, but needs improvements such as a difficulty setting.
4/5
