A somewhat creative puzzle-oriented Zelda-like game by Westwood, unique in the fact that no printed text is used throughout the entire game (also unique in the fact there are THREE annoying, tedious minecart rides).
Some of these, like Error In Check_Heart_On_Screen, can be displayed in-game
Scattered all throughout the ROM are a wide variety of error strings, presumably for assertions strung throughout the game's code.
