Galaxy Brain Invaders

How it plays

• The rack speeds up as you thin it. The cabinet steps one invader per frame, so a full rack crawls and the last one sprints.
• Shelters wear away pixel by pixel. Their bombs bite from above, your own misses bite from below, and a low enough rack marches straight through.
• The saucer is not random. It pays 50 to 300, and the amount follows how many shots you have fired. Count yours.
• Touchdown ends it. If the rack reaches your line, the game is over, however many cannons you have in reserve.

Scoring

Top row squids pay 30, crabs 20, octopuses 10. One extra cannon at 1,500. Each rack after the first starts closer to you, and their bombs reload faster as your score climbs. The counter stops at 999,990.
