This dungeon is to demonstrate that it IS possible to change level dimensions and even the number of levels.
This is a complete copy of the original maps found in the prison.dat (saved game in the CSB prison).
Though, as it has not be done with DMute, you will not be able to see the dungeon in it :(
Well, for those who know already the prison, just kill one more time the monsters.
Bugs: None! This is the original!
