Johnny Test isn't too impressive on the graphics side. It looks like Johnny and his enemies are 3D polygonal models, but I really don't see the reason for this kind of art style. You can tell that Johnny's got some big hair, but most other details are muddled together in a person-shaped blob. The backgrounds do a bit better, probably because there's a much larger area, and they seem to be drawn instead of rendered in 3D. Still, everything is clear, and the screen is generally uncluttered enough to the point where you can tell an enemy is an enemy, and a box is a box.

Music is a guitar-heavy rock track. It's your typical generic rock track, but it's slightly catchy. The sound effects are repetitive little blips and bloops. You'll probably drive everyone around you a little crazy with the constant jumping sound that Johnny makes.

Johnny Test begins with Johnny meddling in his twin sisters' lab. It's all an attempt to get his video games to work on their fancy simulator, which ends up opening it up to other nefarious villains. Johnny knows his parents would be really mad if they found out, so he goes into the simulator to stop the villians and set things right again.

Each level features a different alter-ego of Johnny, with the first being regular Johnny, the next being Johnny X, a superhero form of himself, and so on. Each form has a different special power you can unlock. Johnny has a super jump that will get him to inaccessible points on the map, and that's generally how it goes. You need to melt ice blocks in the second level, so you'll get a fire blasting power to help you do that.

That's basically all there is to this game. The cut-scenes between levels are rather amusing, and feature the banter between Johnny, his sisters, villians, and his dog. These are the parts of the game that feature the art style from the cartoon as well, and they look a lot better than the playable game. It's kind of a shame that the gameplay couldn't feature the highly stylized art from the cartoon. It just barely hints at it in the backgrounds.

I'll admit, I'm impatient when it comes to platformers. Too many "trap" jumps, blind spots, and frustrating enemies, and I often don't see the point of carrying on. Thankfully, Johnny Test avoids most of the annoying aspects of platformers, and keeps the action manageble. One of the ways it does this is with the use of a handy camera. If you don't know what's coming up, you can pan the camera forward and check first.

The levels are fairly short, and don't get too confusing. If you want to dash to the finish and ignore all the power-ups and extra points, you can pretty easily do so. Nothing is really deceptive. Even when doors don't teleport you closer to the end of the level, they sometimes teleport you directly to power-ups or extra lives somewhere on the map. Enemies don't reappear either, so you can keep track of where you've been, based on where the enemies have vanished. It's a pretty forgiving platformer, and really one that encourages the player with praise for each accomplishment.

Johnny Test is, again, your typical platformer. The controls are fairly good, which prevents it from being the sort of hellish, repetitive experience it could be. Johnny is responsive in all his jumping and running abilities, and nothing feels slippery at all. It's pretty easy to recover from mistakes as well, since the ability to guide your landings is generous. If you've ever played this kind of game before, you'll have no trouble picking up Johnny Test.

There's nothing that's going to make someone who's not a fan of the cartoon pick up this game. It's fairly short, and even with Johnny's abilities, it lacks variety and depth. Unless you really enjoy killing time with platformers, it's going to be hard to recommend this game. But on the flipside, it's a simple, rather kid-friendly game based on the Johnny Test cartoon. Young fans may find that this is all they really need in a game.
