Thanks for your feedbacks ! Yeah it was my idea that each time you have to grab a climbing block, you should press a button with the right timing, it's maybe too fastidious I realize... For the swinging part you should get a climber in a place, get the other at the right of the other and let go, with the swing you can reach another block. That's a shame nobody that people get frustrated before the end of the game because I put a particular attention on the ending with interesting dialogs and visuals.
