Back in the 90s I used to have an Amiga 500 computer, without a hard drive but I had 2 floppy drives to cut down on all that disk swapping. There were some excellent games available for the system, plus a thriving scene for tech and music demos.
One of the games that ate up a lot of my time was Lemmings (and its many sequels). The tiny characters spilled out from one end of the screen and your objective was to save them from being squished, burnt or drowned before they reached the other side of the screen.
The music was a mix of traditional and Christmas midi tunes which should have been unbearable but at the time was difficult to get out of your head. Later games in the series lost their simplicity and charm but the climbers, builders and diggers of the original were always the best.
