Party like it’s 1989
I scored two VFD-based handheld games from eBay:
Below is a picture of the game display. The VFDs really confuse the auto-focus on my camera:
The game is a typical shooter, you control the green “ship” at the bottom of the screen and shoot at the aliens above. There are three levels where the enemies move in different patterns, followed by a fourth bonus level where you try to land your ship on a moving platform. The levels keep repeating until you run out of lives.
The other game I got is Invader from Space:
The gameplay is similar to Space Invaders where you lose the game if the enemies reach the ground.
