Hi HakanBacon
Thanks heaps for this very encouraging comment.
Regarding finding that enemy too hard, are you talking about the final boss? If so, they should only be adding 2 shield on turns when they summon reinforcements. If they were adding 30 shield every 2 turns something very strange happened. We're not aware of any bugs where anything like that happens, but if you do see this again please grab a screenshot and send it our way!
Thanks again for playing, and for the great feedback!
