Oops Up looks like the great Pang game. It was created by Silicon Warriors (specialized mostly on Amiga demos) for the Amiga OCS systems, in 1990.
The story is simple enough. You travel in space, through various single-screen levels and you main purpose is to destroy every enemy on-screen. Your gun has many variations, from a simple wire to a laser hand cannon. Surely, Oops Up resembles the Pang title, offering similar playability but adds the sound capabilities of the Amiga to the table, including fully stereo sampled music.
Graphics are not something we should say too much. They are ok, with nice space backgrounds and, well, acceptable sprites. In this game -back in 1990- the most impressive thing was the sound. Programmers wanted to show what the Amiga could do at that time. So they made a re-mixed version of SNAP's famous song Oops Up, and put it on their game, along with some basic sound FX. The music score sounds great and if you have a stereo amplifier you can even start to dance.
