I played the game without any problems, killed the giant sea creature boss, unlocked bombs ect.

Then Janosik automatically updated on GOG, and after that, I can't double jump in my game at all. It's not an issue of skill, as I played the game to this point and was double jumping with ease without any problems.

Tried to rebind jump on keyboard to other buttons, it doesn't help.

I can't finish the game, anyone knows what's the problem?
