I agree, those old shots were awesome. Even being able to play one level of an old build would have great, just to experience it.
As for the platforming, I loved it and never had a problem. The Duke Burger thing was really exciting. Those bouncy flower things, you know where they're gonna send you and that its safe, but when you're so high up its still a rush.
That whole stage, especially when you fight off the dropship on that little platform, and then the encounter with the jetpack alien at the end, all just really cool stuff.
Speaking of Duke Burger, I also liked the trek through the kitchen. That was a cool bit.
