The sound quality on the voices is really bad. Fix that first.
After that... mm. Well, the whole exchange with Hitler is ... slow. Yeah, slow. ... mmmmaybe. You know, it's not really so much slow as it is boring. Try going a little over the top on expressiveness for Hitler's voice. The scene reminds me a little of that character on SNL who used to say "Yyyyeeeaaahh... that's the ticket! Yeah." Don't do it JUST like that, but that's the kind of over the top expressiveness I'm talking about.
While you're at it, do something about the angel's voice too. She's a ditzy receptionist, she needs a ditzy receptionist voice.
The pirate joke is bad, of course, but it's supposed to be. Except: why does the pirate sound like a pirate, but the pirate captain NOT have the standard Buccanese accent? "Yar, it be drivin' me nuts.'
What not to change: the graphics. Well, you could change them a little. But keep the style. Woo, was that slick.
