Inspector (Commodore 64)
A downloadable game
This is a simple detective game where the player has to deduct the identity of a murderer, the time of the deed, and the room where it was done, through a series of questions.
The original code of this game was published in June 1979, Volume 5 Number 6 of "Creative Computing", under the title "Inspector Clew-So" [link], from author Ron Carlson. It was later ported to the Commodore 16 by Andreas Zilla in German language [link], which was the basis of my version.
My version is a Commodore 64 port written in CBM BASIC V2.0, with some visual upgrade, a limited application of sprites, sound and joystick controls. The text of the game was translated back to English, and though the game didn't change fundamentally, I toned down the randomness of the original so the game is more playable.
I expected this game code to grow a bit cumbersome to run on the C64 and planned to compile it to machine code to speed it up, but in the end it runs fine as it is, so I upload it as it is. You can list it and -- if you're interested -- learn from it.

I'm OK with that, however be sure you tested the game meticulously, because the sprite usage limits free memory and if I remember correctly, the BASIC data can spill into the sprite data easily if you expand it. OR you can be a pro and relocate sprite data, like I obviously didn't.
Yep, there's a missing GOTO that would force a return to the start of the control cycle at 1650 when all the functional directions are examined. The program slips into a mini subroutine at 1720 without opposition and runs into a RETURN command which causes the error. Try this line, see if it helps:
1715 GOTO1650
