Phew, I can't even remember everything I got done today.
All that's left now is:
1. Fully implementing the third act (there's some gaps at the moment, so you can't play the game all the way through).
2. Adding all that mysterious "content" I keep mentioning but never explaining (I finished off one minor kind today).
3. Miscellaneous bits and bobs - a few rooms with missing scenery, some stupid actions that succeed, the hints system etc. etc.
I've certainly achieved way more than I expected. I'm not sure I'll meet my self-imposed beta deadline, but unless my testers discover Serious Problems, I should have something to release in the comp.
