Stickman Adventure, Part 39: Up the Ladder

Our hero decides to climb the ladder. The videogame will still be there, he figures, if for some reason he decides to play it again. The climb is long and difficult. The walls are much higher than they seemed from ground level. He passes windows along the way, from which the creepy skull mask figures spectate his ascent. He's never been so close to them. If he leapt from the ladder he might be able to climb into the window.

What would you have our hero do next?
