The tutorial in the README, along with the GoDoc, serve as a reasonable introduction. However, I think it'd be useful to have some more comprehensive documentation written, along with several tutorials on how to use Termloop's perhaps more-obscure features. We could host on GitHub Pages, which would keep it as part of this repo (just uses a separate branch).

Since I figure this would be a simple enough game to run on a Raspberry Pi 3, I downloaded it to my Pi to try it out.

However, I encountered a couple of errors that need fixing.

In the README.md, it'd be cool to have a list of interesting puzzles that users can choose to play, rather than a random puzzle

python3 play_puzzle.py ABCDEFG

For example, including less-frequently used letters like X,Z,Q, or finding 7-letter pangrams, etc...

(also consider scraping previous NYTimes letters: https://www.shunn.net/bee/?past=1 )
