Urgh, that seems to be the inferior MS-DOS CGA version, with no sound I presume.
I faintly recall seeing Temple of Apshai games on my friend's Commodore 64, so I wonder which version is the best? From that era, quite often it seems to be the Commodore 64 version, with best audio and multi-color graphics with smooth scrolling (where applicable).
I've noticed Steam got many other such classics as well, like Hostages! etc. which also were the much inferior PC versions, when the best version on that era would have been e.g. the Amiga version. Oh well, I guess it is easier to re-release (inferior) DOS versions due to DOSBox (not having to deal with Amiga Kickstart licenses etc.).
EDIT: Oh! I didn't realize the Temple of Apshai Trilogy bundle appeared also on Amiga! I wonder if it is the best version of them all? It is quite an early Amiga game, from 1986. One year before Amiga 500 even came to the market, so originally it was released for the original Amiga 1000.
