Hi Aegis, a huge thanks for trying my game and giving such valuable feedback!
I just released an update fixing many of the problems you said, removing cards now is way easier, and now you get a ferret when you start the game! Oh and I also added a new priest card ;)
About the key art that needs improving, do you mean the small icon in the top right when you're on the map?
Thank you again for trying my game, I'm definitely not giving up with this game, I still want to add a lot of stuff like boss fights.
