MotoTrialz is a side-scrolling stunt bike game that's a fairly good remake of the game Trials, but it's not the best in the genre. Like other games of this type, you're challenged with riding a motorcycle over several obstacles in the least amount of time possible. You have a couple of different options for controlling your bike in MotoTrialz: you have gas and braking buttons on the right and you can choose between a slider on the left or the accelerometer for tilting your bike. You'll need to pick one and get comfortable quickly; these stunt bike games are littered with loops, jumps, and all sorts of strange obstacles that require plenty of precision to get past.
MotoTrialz offers all the things you'd expect from a game in this genre. You get 27 tracks that unlock as you play with gradually more difficult challenges. Each track has waypoints that, once passed, make it so you don't have to start over from the beginning when you crash--a necessary addition because some obstacles will be very hard to navigate on your first run. Later in the game, you might repeat the same section of track 30 times to get it just right. Obviously, people who are easily frustrated should not download this game thinking it's a straightforward racer.
While the gameplay is mostly solid, the graphics are not the best. Even with the recent addition of better antialiasing in the latest version, some animation is less than perfect. Specifically when leaning forward or backward, there are limited animation sets to show where your rider is positioned on the bike, making it difficult to gauge just how much lean to use. This becomes really apparent in some of the more difficult challenges because it takes precise movements to pull off certain track sections well.
Overall, MotoTrialz is fairly good stunt bike game, but is lacking in some areas. Still, if you like stunt bike trial games and can get past the less than perfect graphics, there's plenty of challenge and interesting tracks to explore.
