There's a variety of different tracks, including a desert, a river, and even Radaxian, Alex's home. The tracks break off into different directions and are littered with rocks and trees and other stuff, all of which will deplete your energy if you crash into them. Lose all your energy and you lose the game. The graphics in the game, as is expected of an Alex Kidd release, are great. The neat little animations are also very amusing.
Music also rates fairly well.
I'm fairly picky about the music in games, but it's not bad at all in this one. It's distinctively Alex Kidd, and one or two of the little tunes are very similar to those of Alex Kidd in Miracle World. BMX Trial is a pretty cool game.
