RCRPG
Create a simple interactive game which incorporates the following features:
- room-based navigation in three integer dimensions (x,y,z)
- player inventory
- three types of item: sledge, gold and ladder
- a goal coordinate

You are encouraged to solve this task according to the task description, using any language you may know.
Use of the sledge should be required to create a passage between rooms. The ladder should be present in a room (but not held by the player), in order for the player to access the room above him. The gold need not have a function.
This project is based on this blog post by Michael Mol, and the Perl version comes from there.
