This game is amazing but definetely needs some balancing especially with the spell king. Many troops move too fast to be countered after your troops are killed and this needs to be addressed (Maybe a feature like walls around your city).I think the progression needs to be simplified, something like guaranteed card upgrades at certain levels would be amazing (apart from the choice of the three upgrades).Finally, I think making sure that all cards can show up would be great, ive noticed that in some runthroughs cards like the library or the mangler just dont show up regardless of if their coressponding king is active. Bro this game is addictive af, please keep improving it. Cant wait for 9kings
