Not bad!Not bad at all!
The voices were spot on, the song was clever, and the simplistic graphics were part of the charm! It was an amusing concept and was pulled off very well with this flash. It was very well animated, which is a very good thing. A lot of people think that just because a flash has simplistic graphics, it's not worth animating well (just because it works for South Park doesn't mean that it will work for everyone!), but I'm glad you actually put a lot of effort into the animation, good job!
I had a few veeeery minor problems, though: The animation repeated too much during the main course, particularly the one with the robot on the boat's stern went around like three or four times, The Hal 9000 cameo was kinda funny the first time around but not the second, and the Robots all seemed too look similar. Again, just very minor flaws and did not retract from the watchability of the flash at all.
Hope you make more soon!
