The tutorial has wrong keys, despite I had rebind them, it's still WASD

dead forum, sorry, you may have to ask on Steam or contact the developer

So what you mean is that you have changed key binds to your liking but the game tutorial is talking about different buttons based on the default binds?

I don't think you can do anything about that. That's probably a oversight from the dev team and it's not unusual that games include this oversight. For example a cult classic like Deus Ex does have this oversight to this day.

The only way this could be fixed is via another patch or if the dev team would release the source code for the game so the fans could create unofficial patches that improve things. I don't really think that any of this will happen though. The dev team has probably moved on to work on another project.
