While the game requires little interaction for the most part, a few commands will be necessary.
Take "--": This will put an object in your inventory.
Use "--" on "--": This will force two objects to interact with one another. (i.e. "Use 'blade' on 'hilt'" would create a "sword")
Look at "--": This will allow you to look at an object.
Go "--": This will allow you to move in a certain direction.
The rest is simply a narrative journey. Enjoy!
