The Invasion © 2019 Romanow, Lee.

Homebrew game. It's a tribute to Taito's Space Invaders.

TECHNICAL
The game uses keyboard A only. Keys '2' and '6' move the laser cannon left or right along the bottom of the screen. Press '5' to fire the laser cannon. You can't fire again unless you hit a UFO or the missile travels off the screen. Press the console's reset button for a new game.

Choosing a game is done on the title screen by pressing a digit from 1-6 on keyboard A. Difficulty increases every eighth wave with an increasingly slow response to player movement controls. Beginners have the option of starting with a relatively quick response time for their first eight waves.

Only one missile can be in play at a time. In regular games it will explode on contact with an enemy, and you can fire again immediately. Indestructible missiles must travel off the screen before you can fire again. While you can hit several enemies with one shot, missing a nearby target can be fatal.

TRIVIA
Romanow started developing the game in 2018 the year of Space Invaders' 40th anniversary.

SCORING
Your score is shown by the left numeric display. Each UFO hit with a missile increases the score by one point. The highest score that can be displayed is 255 - the next point after this causes a rollover to zero.

You don't score if your laser cannon crashes into a UFO, but you do lose a life. The number of lives you have is shown by the right numeric display. You begin with three lives, so you can only afford to be hit twice. If you are hit a third time you are permanently eliminated and the game is over.
