The game runs slowly on my pc (Acer Aspire V3 772) and I suspect it's an optimisation issue.
The translation in french is not very good, a menu to choose the language would be appreciated.
You can't play with an azerty layout. I tried with a controller (Xbox 360) but I couldn't control the camera.

The first issue would be imo the most important to fix, as it is the one that made the game unplayable for me. It's a shame because it seems to have a great atmosphere.
