This game is a horrible piece of buggery. I can't read the "How to play" thing because it zips by at 1 page per milisecond and I have to re-disable the HORRIBLE sound and music all the time. Come on, these are the bloody basics...
do you think climbing sucks?
start climbing training and put something on your keyboard to hold space down. check back after a few minutes and continue ;)
the controls are a pain in the ass on a german keyboard (Z and Y are swapped) and changing the keyboard layout doesn't help.
i will play this via gamepad though but others will complain and not have a workaround I guess.
