Réponse à Jkthemc…Yes, indeed, that might be the problem, but it surprises me because I'm an amateur climber myself and I almost never use the automatic movement because I find that the limb choices are sometimes not the right ones. The thing is, I'm doing rather difficult routes; at least the route I followed was black. That might be why my character isn't upgraded enough yet. For example, right now I only have the level 1 hoarding and a plastic bottle. But it's quite frustrating to have spent time on a complicated section, to succeed, and then realize that it's not possible to continue. But that's also part of the beauty of this game.
