OK, I think I hit a pretty good spot to quit for the night. I got a lot done...at least all of the basic functionality and the special items.
Tomorrow, add some more game flow logic, further playtesting and tweaking (this game is going to need a lot of that), maybe some additional enemies.
It occurs to me that I haven't described my game here; maybe I'll do that when I get home.
So, off to home, and to bed!
