Dr. Plummet's House of Flux is a computer game developed by MicroIllusions in 1989 for the Amiga.
The unusual Dr. Plummet has invited the player character to his House of Flux to test the player's skills on four different missions, each with seven levels. Each level has a specific theme, with differing backgrounds and obstacles that relate to that theme. The player flies a ship equipped with a gun and shield to rescue six astronauts held captive in each level, avoiding or destroying obstacles such as walls, guns, bases, and weird things created by Dr. Plummet.
The player operates the ship using a joystick. Moving the joystick to the left or right rotates the ship in a counter-clockwise or clockwise direction. Pushing forward on the joystick thrusts the ship forward. Pressing the joystick button fires the guns, and the space bar raises shields that protect the ship from some obstacles and enemy fire. Running out of fuel causes the ship to rotate aimlessly.
The game was reviewed in 1990 in Dragon #157 by Hartley, Patricia, and Kirk Lesser in "The Role of Computers" column. The reviewers gave the game 2 out of 5 stars.
