Motocross Maniacs

The Good
This is one of those simple games that doesn't really look like anything at first glance, but then you get into it, and it becomes really addictive. The learning curve is fantastic, starting out easy, then each level introducing a couple of new obstacles. There's about 30 levels I think, and the last ones are insanely difficult.

The Bad
The graphics certainly aren't quite up to standard, but this does not detract from the gameplay. I can't think of anything thats really that wrong with the game.

The Bottom Line
Basically, you drive your motorbike along a course with various jumps and obstacles. The first few levels aren't too hard - you could probably do them just by holding down accelerate. But later on, you need to use nitros to make it over a jump, or to gain access to a secret area. You have a time limit and a nitro limit - you can pick up both along the way, though usually you will have to sacrifice a nitro to try to get there.

You can play single player, with the CPU, or with another gameboy.
