I'm a developer. So I personally know how easy it would be for a game company to implement such a feature. That's far from the hard work the game itself requires. But that depends how the code is written of course.
What I really don't understand is that only one administrator replied so far to a message that had been posted when only the first episode was available. And now that we're getting to the end of the series we still didn't get anymore feedback.
This is pure laziness from one or multiple developers. That doesn't mean all the developers are to blame in this mistake. But you know in companies sometimes you have good employees who work hard (like for the scenario and even the game itself) and some lazy ones who care only about their paycheck.
It annoys me to know that people like that are allowed to earn more money than me with that poor mentality. But I guess they can't afford firing those. Things like this usually don't happen in bigger companies.
We can find some workarounds to all these problems. But that means the clients (gamers) have to finalize the job of the sellers. It's like you go buy a brand new car and the guy tells you that you'll have to buy and mount the wheels yourself. Or find another way if you can. But they won't ever consider helping you.
So this is causing multiple problems and for me all apply even some that haven't been discussed on this thread.
- I live in Europe (sorry for that

) and thus have an AZERTY keyboard like for most countries here
- I always play with inverted Y axis (sorry for not being what you would call "normal"

)
- oh btw I have an integrated Intel graphics in this computer ... yeah I get like 1 frame every 5 seconds during animations (even if the overall configuration is far enough for this game). For example I have no difficulty to play games like ArmA2 on this computer with the same FPS as most players. So I don't get it.
- more than that I had the compatibility error when I first started the game so had to find the solution online and run in compatibility mode for... Windows 98 ? really ? ...
So yeah, I can switch to English keyboard to use my ZQSD keys, I can probably find a utility to switch vertical axis (maybe ?) OR I can buy an XBOX360 controller (I have an expansive controller but it won't work with this game of course) and finally I can buy another computer that suits better for this game...
