There are a couple of "if debug then" statements.
Most of them will not work unless you start the game in a "debug" mode.
At least this is the case with "GOD" and "GIVEALL".

Entering debug mode is most likely accomplished by passing a command-line
parameter to the game or adding/editing values in a configuration file.
