For the demo version:

 I had a look at the Demo and realized that this game has many script
 files (ending with .cs) and that they can be edited with a normal
 texteditor! So you can add your own commands there.

 One command is: 'KQMonster::god <Monstername>'

 If you alter a script by adding the line

 KQMonster::god Connor

 you will switch into the god-mode.

 E.g. in the swamp-level there is the script '\Swamp\KQ\watpump.cs'.
 Just insert in the e.g. 8th line right below 'KQSound::play slurp.aud'
 the line 'KQMonster::god Conner' and when you will drink form the
 waterpump in the swamp level you will switch on the god-mode.

 You can find all the commands by searching through Mask.exe file.
