Well I took you code and pasted it into a file and went

$ ruby dungeonapp.rb

It works for me and should work for you.

However the is a bug. The class is called Dungeonapp but you then do this

my_dungeon = Dungeon.new("Fred Bloggs")

Use only one name or the other.

Also I updated the end bit to

my_dungeon.start(:largecave)
while true
  print "go where? "
  go_to = STDIN.gets.chomp
  my_dungeon.go(go_to)
end

and had to change this

def find_room_in_direction(direction)
    find_room_in_dungeon(@player.location).connections[direction.to_sym]
end

Note the to_sym on the end. You cannot type a symbol in interactively so
you need to convert it.

A good start, keep it up.
