Actually pretty good
Graphics(8/10): The graphics are kinda good. The 3D landscape looks awesome, and the characters look pretty good.
Gameplay(9/10): Its pretty fun. Sometimes the enemy AI is annoying, though, because they sometimes just like bounce around in the air really annoyingly and sometimes they pick up the items you throw at them and throw it back at you. But I still manage to beat them, and the game is actually pretty easy to say the least. The game actually runs on the same engine as the game known as The Powerpuff Girls: Chemical X-traction, which my older sister got for the PS1 when she was younger. I actually noticed this once I saw the game menu, 'cause it is no doubt like the menu in that game. At one point of the game, you have to fight yourself(the clone is a palette swap like most games).
Sound(8/10): The music is awesome. It sounds alot like classic Tom and Jerry music. The voices are also pretty good. Jerry's voice role is very fitting, and Tom's voice also suits him. The characters don't actually talk, however, Butch seems to in his Intro(he says "I'm good!"). People say the sound effects are annoying, but to me, they sound fine. I really don't get what the deal is, but the sounds sound fine.
Replay Value: There are unlockable characters in the game. At the start, you have Tom, then later, you unlock characters like Jerry, that duckling, that grey mouse, the bulldog and his puppy, and Butch(from many episodes, but I know him from Blue Cat Blues). The game doesn't get to repetitive because it is randomized.
Overall(8/10): The game is pretty addicting and I really enjoy playing it. The game is kinda hard at points, but is more easy then hard. I'd have to say, I am actually impressed with this kids game. Mostly, these games based off kids shows usually suck, but I actually like this one. Not only that, this game is better then The Powerpuff Girls: Chemical X-traction because there actually is a jump button and a bigger selection of characters. The Powerpuff Girls: Chemical X-traction just has the main three girls throughout(if I remember clearly). So overall, this game deserves an 8.
