Notes
This game was unofficially ported and extended by Zeljko Juric, in the early 2000s, as a demonstration game, using his version of the Quill for TI-89 and TI-92+ graphical calculators.
A modified version of the original C game was produced in 2022 by retroprogrammez.fr, which will run on Windows as well as Apple IIe.
