Love how my kingdom looks, artwork is awesome!!! Only one issue...used my crystals for new avatars....of which their are now none :/ I are sad puppy....
Think to add an edge to this game you should introduce a leader system, where for...lets say...attacking a higher rank than you will have a chance of creating a general....who adds randomly generated bonuses to your army (passively, not a real soldier), or if you focusing on resources maybe a production leader could pop up, passively increasing production speed/resource speed. Think these leaders should cost either a set sum or a percentage of your resource income for a set number of days (e.g. 10% income for 10 days, thereafter no charge), or to make yourself some income make three insane leaders that cost 15 gems or something, giving the paying customers a slight smile on their faces :)
