What I'm talking about is demonstrated here (at 1:07):
I believe the hammer has to get stuck in one of the notches in the wall, but getting it to get stuck is very difficult and the physics there are extremely fidgety. And also, once it gets stuck, how should the mouse be moved so that the character's head reaches the goal? It feels like where the mouse is moved and where the head goes is not always the same.
So is there some way to do this easily that I'm missing?
As far as I can tell you should place the hammer in the corner of the wall and not move your mouse off the area where the wall is and the best place to put the mouse is just above the hole in the wall but even then the characters head seems to move at random.
Thanks for your response. Through testing I found that pogo-ing up towards the face and hitting the wall with the hammer diagonally downwards can send you in an upwards trajectory. It's very specific but if it's done right you can get to the face without needing the glitch. I did it in my most recent pb. I think I will stick to that from now on since the glitch is so fidgety.
You can first-try the glitch fairly consistently by bouncing off this region of the floor: https://imgur.com/a/GSuXW
...and then quickly driving your hammer into the notch, while you're still airborne. I think the reason why this works is because it gives your head a little bit of extra height.
Zurcio used this in his run, and you can tell this by the orientation of his hammer (it's clipped into the ledge he's standing on and angled upwards) when he finishes the game.
