Bronco

Bronco, a Western arcade shooter.

I took the concept of a Galaga-shooter, and added my own spin to it. I made this into a Western theme. The sprites, which I drew, are of cowboys. The sound effects, which I made through GarageBand, reflect Western "sounds" such as revolver gunshots, horses, and dynamite explosions.

The basic concept of a 2D, top-down shooter is the same; there's a player that moves in all four directions and there are enemies that you have to shoot.  I added a start screen, death, and win screen. 

Use WASD/arrows to move, and "Space" to shoot.
