Don't know how to reach the dev, but can at least post here.

Rebinding keys doesn't work properly. I'm left-handed and usually use OKLÖ instead of WASD. If I bind to that, the back key is comma, but that opens the menu. Shifting everything left one step so it's IJKL instead, the M becomes the back button, but that one not only moves back but also immediately moves to the "home" position of my village. I've double-checked that there's no duplicate key bindings, but some seem to be hard-coded.
