I finished my game! My original idea was to:
1. Make Hangman more complicated for no good reason
2. Nest games of Hangman inside each other, in order to accomplish #1
I completed both of these, but during playtesting I found that the game was actually pretty fun as well! Bonus.
So I hope some of you are able to play it in a family restaurant or a classroom someday.
Edit: I made a video that teaches the rules, since it seemed hard to explain in writing. I recommend learning the game this way.
