I found a way to reach the roof:
I jumped down from the warehouse-wall to the 1st big box. I did a 2nd jump to the two stacked boxes. Then i wanted to jump to the next boxes near the roof, but instead i jumped through the roof and landed up there.

I was able to do that from the very beginning.gmi wrote:Dear Remus,
