Santas Present Drop 3

In Santas Present Drop 1, you helped Santa drop the presents down chimneys as he flew over numerous rooftops. In Santas Present Drop 2, Santa was unhappy that presents were being delivered to the wrong people, so he installed the Gift-o-Matic 5000. However, whilst flying over the Alps, the contraption exploded scattering presents all over the mountains.

Luckly however, Santa had his skis with him. Your job is to guide Santa to collect as many presents as possible within the time allowed.
