Maybe it's my memory from 20 years ago playing tricks on me, but to quote Civvie 11: "It's like playing a version of [Extreme Tux Racer] where everything was moved two inches or so to the left."
I also played it back in the day and it seems perfectly accurate to me, at least in terms of control and physics. After a few goes I'm quickly approaching my old personal best on Who Says Penguins Can't Fly. One thing I'll note is that the "best score" display seems to be only based on time, not herrings (which I actually prefer, but I know that's not how you're supposed to play it).
