A meteor wave is threatening the earth.
Other digital platform
Commodore's VIC-20 is a computer from 1980 with 5 Kilobte of RAM of which 3.5 KB are usable to BASIC. My game uses a little under 2 KB. Made with BasEdit.
Runs on unexpanded PAL VIC-20 with Lightpen. The lightpen needs a trigger (joy left) and calibration inside the program may be needed. You will also need a CRT-display as lightpens will not work with modernn TFTs.
