DS Critic Reviews

If you can get over the length of the game, Johnny Test isn't that bad of a platforming game. It looks decent despite Johnny's lack of detail, the music is fairly reminiscent of what you'd hear in the series, and the general platforming and difficulty level are fine for the intended audience.

On its own, Johnny Test is a fun little side scrolling platform adventure. The levels are a challenge and the Johnny Test world comes to life on Nintendo's tiny handheld machine. The only problem rests with those who watch the show as they will likely find this game too much of a challenge and may likely pass this one up for more forgiving options.

There's nothing broken here, but it's entirely worthless. [May 2011, p.71]
