An American Tail: Fievel Goes West is about a cartoon mouse who must make his way to the Wild West based on the movie of the same name released back in 1991.
The player must either fight or avoid cats and other obstacles as he strolls westward. The game is side-scrolling with a side-view of the action at nearly all times. The character is armed with a pop gun that can eliminate the bad guys using a non-violent approach to the Wild West genre. An NES version of this game was planned. However, it was never released.
