Well, at least this is a linear adventure game. Just be prepared to write down the correct answer, as most options are "game over and start again." If I recall, at least the first couple were: 4,3,1,3.
It's on the subject of a private tutor and school girl, and apparently involves a lot of zipping around on motorcycles. The adult content is uncensored, but a ways into the game.
Allegedly, there was a sequel in production... in 1989.
