To celebrate and promote Chu Chu Advance coming to GBA, Sonic Team has cooked up a 25-level demo for the public!
Sonic Team has posted a 25-level demo Shockwave version of Chu Chu Rocket online on its Japanese site. It looks like a good game, but it is entirely in Japanese (and for some reason Babelfish won't work for the directions). You're free to give it a shot, but knowing Japanese is definately a plus--especially if you don't know how to play the game already :-). To get to the puzzle front page, click here. If you want to jump right into the game, just click here. Have fun... and good luck!
