So am I allowed to go full World War 1 infantry charge, soldiers running across the field and storming the enemy? Preferably screaming out the Greek national anthem?

Of course, There's not much in the way of tanks on Crete, it was a mainly infantry-based battle. There were some, but none of them were suited to anti-infantry duties and suffered mechanical problems. 

At the moment, I think has been stated, the Germans are just trying to get into cover so they can recover their gear. You'll meet some fumbling around with a knife, and others who have recovered their weapons (I think 40% of the armament were MP40's?) will be fighting you back with a "live or die" mentality. The Fallschirmjager were formidable troops, later serving as the Third Reich's praetorians alongside the Waffen SS, so they'd know what they were doing.

EDIT: 25% were armed with MP40s, after a quick wiki search. The Kar98 made up the rest, with MG34s scattered in-between.
