Cheats are activated by typing "BALDRIC" during a level.
Once actived, your score is reset to zero, and you can
press the following key combos to achieve what is listed:
[Left Shift]+[R]+xx - where xx is a number of a room to jump to (01-45).
[Left Shift]+[H] - to get maximum health, also food and drink.
[Left Shift]+[K] - to get all keys except the end tower key.
[Left Shift]+[W] - to get full weapons.
[Left Shift]+[C] - to get ten coins.
Note: Only the health cheat works in the shareware version.
The rest require the registered version.
