I just found the CASTLE adventure. There is a remake over at: https://www.classic-retro-games.com/games/adventure/castle-adventure-498
but even better is the original, which you can play online: http://www.dosgamesarchive.com/play/castle-adventure/
(Edit: although if you’re serious about playing it, you should run in a local DosBox such that you can lower the clockspeed- otherwise you can’t beat any foes)
