If you press the (tilde ( ` )) key while in a dungeon, a text box will appear.

so far the only commands I found out is:

addexp (if you type 10 in the box, it will give you 1000 exp)

spawnitem (exact spelling of item ex. soggy sandwich)

forgetmap mapname (map name ex. "Abandoned Barricade" should all be in in LOWER CASE (ex. abandoned barricade) and you shouldn't be on the map you are resetting.)
