I really enjoyed the beginning story and made it up to the mountain and then I could not proceed...
I was able to look around on the top of the mountain and would crouch with 'c' and use 'q' to whistle, but unfortunately could not move, as the WASD keys didn't work. Seems I am the only person with this problem and after reading the comments was really looking forward to playing through again, so I restarted but had the same problem :(
Thanks for submitting, I really wish I didn't have this problem...
