I've modified my path a bit which allowed me to save some time. Now Dora is saved as third of the Yolkfolk instead of first. Beacuse of this I've noticed that when you put Dora on the ground she becomes invisible, but is still there. So you need to remember where she is to pick her up later on. Apart from that I was able to avoid most of the minor mistakes and deaths. I'm pretty happy with this time.

PS I think I've found another time saver and will try to beat this record.
