Oh No!

Oh No! is a fast paced shoot'em up with multi directional scrolling. Taking
place in the far far future, you'll take the role of a ox breeder. Using your
ship Badjak, your objective is to prevent aliens from taking away your oxes.
To your disposal you have two kinds of weapons, a laser and a boomerang
weapon shot from the rear. You can get a new ox if you destroy one of the ox
