It's a slight pity most of the nazis later on don't sound quite German anymore, especially the main antagonist (to me) has more similarities to a certain famous Italian plumber than a German. The guard guy in the beginning however was spot-on, also one of the nazis on the plane came quite close (guess same voice-actor) :).
To the voice-actors in question: Please don't let this comment get you down! I can only imagine how difficult it must be to do a convincing fake foreign accent, especially if you have to voice several roles at once. It's just how I as a native speaker perceived the whole thing. Guess every non-German speaking viewer won't have a 'problem' with being convinced anyway :).
Apart from that it was funny, the animation was done well, almost pissed myself when I saw the hitler-masks. Loved how much detail you guys put into the background/'stages' of the story. The James Bond-style showdown was awesome (somehow couldn't stop laughing when that parachute popped up). Please make more :).
