Anyone figure out how to remap keys? This is a critical issue for me - renders the game unplayable actually.

Can't be played with mouse only? If it can't no binding will be a no go for me too.

The game can be played with mouse only - you can move, fight, choose the dialogue options. But all of this a bit longer that way.

I see thank you it could work for me with turn based, I often choose mouse only despite some keys would speed up some stuff. I probably can go over the lack of rebinding.

If you really need to rebind keys you can use 3rd-party key mapping tools such as AutoHotKey.

However I agree that the mouse support in this game is great, so you probably won't even think about needing keys...

The key binding have been realized in last update.

That is true - I only realised this after I grabbed the latest update (which was just after posting the above - hadn't noticed since I was taking a break from this after completing it about 10 times in a row).
