I just learned that I could slap together something with at least minimal gameplay and a reasonable end-game condition in less than 8 hours of work.  While I got very little actual game out of the exercise, it instilled a strong reminder to structure one’s software properly from early one.  I still look forward to writing up the full post-mortem later.

Good luck, everyone!

Addendum: I just added the keyboard control scheme to the webpage.
