On a completely fresh installation of KeeperFX (I've only tried version 0.4.6) when you go to the options menu and press 'Define keys' to learn/change the keyboard controls most of the left side of the menu is empty. (See screenshot)
To reproduce clear out your 'save' folder, launch the game, go to this menu and scroll down a bit.
I noticed the installation package contains a 'settings.dat' file in the save folder. This should not be there, and when it's not, this issue is fixed.
