Matt's Adventure Game written in GNU Make

So, I was working with a really funky Makefile at work, and realized that GNU Make is a pretty darn powerful language. I wondered if I could write an adventure game in it - so I did. Here it is. To run it:
• Make an empty directory.
• Download
Makefile to the empty directory. NOTE: if necessary, rename the file to 'Makefile' if your browser added a .txt onto the end of the filename.
• Type 'make help' (or 'gmake help' if GNU Make is not your default make utility, such as on *BSD systems).
