I suppose this could be called an adventure, since it involves text input, but is very strange, and not very playable. To start with, play is in real time. Movement is by walking in a set direction.
Vocabulary is fairly minimal, as are the text replies, and often, entering a direction such as NORTH, which I reckoned would turn me the right way before WALKING, met with a "Which way's that?"
A TELESCOPE command puts a cross-hair on the screen, which can be aimed at anything in view for a graphic magnification. Well, anything that is in the same horizontal plane as the cross hairs, for they can only be moved left and right.
Pictures can be turned off, in which case it seems you are almost playing in the dark, for WALK brings no response at all.
The inlay expands, and has comprehensive instructions, but sadly that telescope is needed to read them!
