I really don’t see the big problem here.
Yes it’s a hard puzzle, took me about 1.5 hours to do, don’t expect to do it in a few minutes.
I didn’t notice a big camera problem, what control settings are you all using? I have it set so I just hold right click and move my mouse to turn, that way I wan just hold ‘W’ down and keep turning my mouse to navigate the puzzle.
The problem of other characters shouldn’t matter once you’re past the first section because if you aren’t at the front of the pack you simply aren’t going fast enough, you’ll never make it anyway.
I think you’re all just trying to justify your inability to do the puzzle.
