If anyone gets 0 xp and silver, reload the page, the game got an update. In addition, if you supported the game for greenlight, you now have some gems too. (you may need to reload again)
there needs to be more units to capture like maybe after archer there could be sniper (elite archers can come with a knight and will come with a lord) and for after knight royal guardsmen (a jack of all trade unit that comes with Lords)
possible new summoning recipes
sniper> Dark archer
royal guardsmen> Dark guard
doctor> healer's assistant (not as good as a priest/priestess)
Thank you for your suggestions. We will think about them.
