Magica (Public Domain)

Originally an Amstrad-only game (I think), but now also available on the Amiga.

When I saw the fairies and how they seem to pose no threat, I did think there might be something special about them, and when I completed the game it said to try and not kill any of them next time. Being curious what might happen if I didn't kill any, I checked the file for the message and found the same message about 'gratz, all potions collected...' twice, and only one of them had the fairies message, so I assume if I did replay it and kill none of the fairies, the end message would be the same, but without the 'don't kill the fairies" part.
