I add this issue here, as it's not discussed under the support section, but it's definitely a support issue.
The main issue is that the walking dead game doesn't allow the keys to be modified. This is particularly serious for owners of keyboards different from QWERTY (for example, AZERTY as seen in France, where you sell the game). The default setup is unplayable on these keyboards. This is a very easy issue to fix, by allowing to set his own keys.
I'm not the only one to suffer from this, as you can see in the forum thread:
Please correct this asap as it's an industry standard on games to be able to change the default keys.
I saw it on PC, but I suspect it's everywhere.
