Okay. If you must know I've tried all these cheats and they work, so here they are:
Press ctrl + alt + c During gameplay and you will hear the sound of a door closing then type any of the following:
now the rain has gone = complete realm revealed.
this is my church = all rooms become available to build.
fit the best = all doors and traps become available to construct.
i believe its magic = all spells become available.
show me the money = gives the player gold.
ha ha thisaway ha ha thataway = gives the player 100000 mana. (only works in version 1.7 of the game or higher.)
do not fear the reaper = wins the current level.
Let me know if these work.
