OK 1st suggestion I have is a suggestion forum. Nearly every game in aeriagames has one.
2nd is to fix the battlefield. I hate not having a confirmation button on exiting when i accidently click leave while i'm in the middle of battling. Put an exit button somewhere else or make it have a 2nd confirmation that pops up at the top instead if right in the middle of the screen. I hate accidently leaving early :/
Would also like to see some other fortifying charms at some point if that might happen. Or special events where exp and fortification are increased or something. :p
I have a few other ideas but i'll stick with these for now.
