This is the first game i ever played, on a DOS (i think) 286 computer with green monochrome monitor.
This is where it all started for me!
Surprisingly, looking back at some of its mechanics, it was metroidvania for PC. Same style roadblocks that you can't get past unless you have a certain ability, experience and leveling up, bosses after a level, multiple different towns (well, "different") and dialogue.
It's definitely worth preserving!
