I tried to play the game, but couldn't manage to leave the living room as the game instructed me. The L command is used in parsers to "look" at the room, so the engine would just give me a description of the room rather than letting me leave...
The issue wasn't much looking at things, but leaving the living room. I tried L (as the game instruction) but it parsered Look instead, and LEAVE, but it returned as undefined.
