– Contents

This is a 3D maze game in which you run around trying to catch your opponent. The square at the back represents the end of the current path, and your current position is shown by the trapezoidal area. Also, if you don’t align yourself perfectly with an entrance while turning, you will hit the wall and the game will end.
Pressing F and H turn you left and right, respectively, and pressing either V or B turn you backwards.
If your opponent is in front of and less than 1 block away from you, the game automatically makes you catch them. The bottom of the screen shows you your distance from the opponent in both the X and Y coordinates.

– About the Program

For this one, I’ll be explaining the music compiler present at lines 740-780 and from line 1600 onwards. Z$ may contain the characters”4567CDEFGABHR”, which correspond to the FGABCDEFGAB notes (+ rests). Afterwards, the subroutine at 1810 is called, which then uses the subroutine at 1670 to POKE the pitch and length into memory.
Then, by assembling the machine code with the subroutine at 1900, the routine at lines 740 to 780 in the main program plays each note, repeating the tune over and over again.
If the sound pitch happens to sound wrong to you, you can change A(pitch) and B(length) in the IF statements starting at line 1670. For playing long notes, use something like “AAA”.
Lastly, while typing in this program, press CTRL+G(BELL) several times inside line 1000’s PRINT string.


Kage: Hmph, yet another 3D maze game? Those are getting boring by now!
Editor: No, it’s not! By using its music compiler, this game can play the “Forbidden Games” theme as you move. Isn’t that amazing?
Kage: Hmm, I didn’t know that. My bad!
