Parents have nothing to worry about, Chu Chu Rocket! is as wholesome as they come. The only thing that might be seen as marginally objectionable is the fact that some mice and cats do fall to their death and some mice will get eaten—but it is not done graphically or gratuitously so it should not be a problem. Chu Chu Rocket! is one of those games that belongs in every gamer's library. Even those who first experienced this puzzler on the Dreamcast should give it a try (at least as a rental) to see it hold up on a handheld. There is nothing like taking Chu Chu Rocket! on the road. Multiplayer Game Boy Advance fans should be aware that thanks to the simple graphics, four-players can play on one cart, so all you need is a link cable and a cart to get a good multiplayer session going. Special features like Team Battle and Four-Player Battle are sure to offer loads of entertaining playing sessions among friends. Gamers playing alone will also find something to love about Chu Chu Rocket! thanks to the 2,500 (it is still an unbelievable number no matter how many times I say it) stages in this little game pak. If nothing else the customization modes should keep you busy for a long while.
