Debug Mode
The following debug keys work for version 1.1 of Halloween Harry only: [Ctrl] [R] [E] [N] - Gives you all weapons, and activates god


mode for several seconds.
[al
[L] - Level warp. Type the number of the episode (1-4),
followed by the number of the level (1-5). Illegal
input will dump you to DOS. This can not be used in
the shareware version to access levels in the registered
version.
[al
[=] - Change location within a level. Type coordinates after
this code; illegal input will probably crash the game.

coordinates you are at on the level. This serves no real
function on its own, but it is used by Apogee's Game Hint Line
sometimes to locate a player in a level.

[rshif
[F12]

Misc Command Line Parameter
"skip" will start the game directly from the main menu.
