Nice one. I played it back in 1994 or 1995, along with Police Quest IV. I had to purchase a hint book, 'cause I could not solve it by my own. Recommended to adventure game fans. I love the story twist in the middle of the game
BTW, don't want to be a nitpick here, but IIRC the character name is Callash, not Callosh.
I must say I'm surprised to see Dragonsphere here, though. I remember the request being rejected in the past due to ESA protection. If it is okay for Dragonsphere, perhaps we can get Rex Nebular next (unless it is considered as a mature game)? Or, is it already hosted on Abandonia as well? (Too lazy to search)
