Rolling maze in requiem...

[ShnitzelKiller]

It's absolutely impossible. All the lasers aside from the two on the right flash really really fast, at least faster than it's possible to roll the thing. What do you do there?

Do you mean the puzzle where you have to roll that 'ball' thing?
Roll it at the left corner. Don't try at the middle or right. Just go to the left and I guess you figure the rest out for yourself.
