@aurel12048 The Invisible Man, as far as I know, only appears in one map in one particular room. If you've figured out the basics of how the game work, then you'll know where to find him. If another doesn't appear in it's place, that is.
Telling players how many characters they've got unlocked on the the character select screen (yyy of zzz characters or something similar) would be nice. Also: halfling ranger all the way.
