Hey FreedomFries,
Thanks for the support and playing the game, really appreciated. The dungeons are randomly generated so I can't tell you exaclty where to go but there should be a room with a hole on every floor untill the boss. sometimes its not so clear that you can go down from a room, there should be a room you missed somewhere.
Dead zombie bodies return as red feral zombies after a certain time,
Rafi
