sure. During the game, type [,] [c] [h] [e] [a] [t] (a comma before the 'c'). You should then get a message 'cheat mode on'.
Then the following functions will be available:
- ,heal (as above, type [,] [h] [e] [a] [l] during the game)
- ,map (will display a map of your current game world location, including the areas you haven't explored yet. Clicking on any position within this map will teleport you there)
- ,quest (will display your quest notebook, plus a list of quests you finished)
- ,pos (will give you the coordinates of your current position within the game world)
- ,telep (will teleport you to a game world location specified by coordinates such as received via the ,pos command)
For 'god mode'-like playing, simply keep the [W] key pressed during combat, automap, travel screen, bartering, using/taking objects etc: This will make everything available/succeed, in almost every situation. (But playing the game that way really isn't much fun.)
