A Public Domain version of "Dr. Plummet's House of Flux"
This game was originally shareware that Scott Peterson created as a summer job in 1988.
You could get full game at that time, however,
Scott send information of bonus points to you after you sent money to him.
Unfortunately he died at the young age during his first commercial development,
"Dr. Plummet's House of Flux".
It was March 19 in 1989.
In 1990, Richard McGowen also redistribute that shareware version "GravAttack"
as a Public Domain.
know that "Oids"
was the first title
as 16 bit computer game inspired by "Gravitar".
It was released in 1987 as commercial game for Atari ST.
As Amiga games, this "GravAttack" was the first one.
Fortunately for Amiga users, it was a free game, and had some nice features:
• The power of gravity changes at different levels.
• The direction of gravity changes at different levels.
• Each level has specific tiles for walls and backgrounds.
• Secret bonus points are hiding.
"Local Secret Bonus" hides in a specific level.
For example, you can earn 600 fuel & 2000 points
after you complete the 9th level without destroying any turrets.
"Universal Secret Bonus" hides in all levels.
For example, you can get 1 ship after you get a specific key first.
The aim of the game is collect all keys in each level.
After several early levels, you will notice that a lack of fuel is a critical factor.
After your fuel runs out, the game would be over
even if many ships remain!
Needless to say you must find many secret bonus points as possible
if you want to play later levels on your real hardware (= without saving states).
