Base Invaders

This interactive token features a demo version of a classic game combined with an art generator in an Opepen frame.
The game plays infinitely and automatically, and each time the "BASE Invaders" are cleared, a new background scene is generated and a new group of invaders arrives.
To start and restart the demo, press the left button. To change the background scene, press the right button. To move, press the left and right arrow keys on a keyboard. To fire, press the up arrow key.
