It's roughly a 'roguelike' - i.e. a difficult, simple-ish RPG with some degree of randomised content to increase replay value. Originally created in the 1980s as far as I can discover, and it shows. I haven't played it much but I plan to try.
A couple of screenshots for the road:

If you want to try it out, you can download it from old-games.com here (though you have to buy at least a one-day subscription).
You'll want to use the 'Download - Easy Setup' link on that page, because that will give you everything you need to run the game just by extracting (with something like 7zip) and then double clicking it.
