Talespin

Talespin is an adventure game creation system made by Mark Heaton and his family (wife and their five children), which allows you to create interactive graphic- and text-oriented adventure games, demos, books, tutorials, or whatever application you can think of. It offers graphics, 100 development commands, mouse control, no copy protection, hard drive support, and Telltale, a run-only module that allows users without Talespin to see your work.

Talespin also includes two sample adventure games: The Grail made by 19-year-old Rudyard Heaton and The Wolf made by another artist
