Toy Story on the Game Boy is fair and it's surprisingly good.
It follows the movie well. You play as Woody throughout levels based on the film.
Game play:
The game play is sometimes easy and sometimes hard. In the 3rd level when you're trying to race Buzz Light year, sometimes you'll have a hard time getting Woody's pull-string to hang on the poles.
In the level when you're inside the Crane Machine, it's sorta hard getting through the level because of some projectiles in your way.
Sid's house is another hard level because of the enemies, and jumping from platform to platform some of the times. But overall, the difficulty is just right.
Graphics:
Another flaw besides some of the hard game play, is the graphics. The graphics look like 16-bit. I mean, this is a 8-bit cartridge, the graphics should be 8-bit. But the character models look great though.
Controls:
A for jumping and B for shooting.
Music and Sound:
Only two songs from the film are put in this game and they sound just good for 8-bit. Sound effects are good as well for 8-bit.
Lasting Appeal:
A good and fair game based of the 19-95 film, only with a few flaws. 6 out of 10.
