Radical Castle : Christopher Wigginton : Free Download, Borrow, and Streaming : Internet Archive

An adventure game made in World Builder, the system also used by the Ert series, the Ray’s Maze series and the original versions of the Lucy’s Worlds series. Both typed commands and point-and-click are used. Many important commands are listed under the Commands and Weapons menus.

I wasted hours on this game, but never did get to the end. I always seemed to die at the same place.
