Boring and hard to control.
The game was hard to control. The characters would either move too fast or too slow and this wasn't only because of the goo. For me the chararcter kept on doing things I didn't want him to do like slide up ramps. The game was also easy to win but the only way to move forward to get more cups was to get stars. The levels were very boring because they were basically all the same. The levels would be squriting each other, point catching, throwing food, connecting tubes, and throwing baskets. The only thing that change was how the level looked.
Graphics:
The graphics were pretty bad. The character that looked the best was Zim. What is sad is when a 3D chararcter (Jimmy) looks so bad in a 3D game. Some levels look nothing like it came from a show. Zim's base looked like it was a toyland.
Sound:
The characters tended to be hard to hear other that Zim laughing. The host Cat (and Dog) had a odd voice. The music in the game was down right annoying.
Value: The game is not wroth the money therefore I think you should rent the game first.
