Oh yeah, the jumping. I can understand, we took like 15 minutes to complete one jumping section.
It was a series of progressively higher pillars that you had to jump on, and halfway through their depth position changes so you had to judge how far you should walk in before jumping to make the jump, but walking too far in would cause you to fall off the pillar you were standing on.
Quite frustrating cause the camera is parallel with the environment, making it harder to judge depth.
Especially when all 4 people have to get up there.
