The month is not over, but I am heading to DragonCon for a week. So you get your report early. Conveniently this allows me to report "not quite done yet" without too much slippage past my mid-August deadline. And without smacking into the more realistic end-of-August deadline.
It's not quite done yet! But at least the update posts are getting closer together, right?
At this point the entire puzzle-line of the game is playable. That is, you can start at the beginning and solve every puzzle. (Without using cheat or debug commands.) This doesn't end the game; it leaves you in a state marked "endgame", although "denoument" would be a better term. It's the wrapping-up sequence which leads to the ending text. There are no puzzles here, but it's an interactive sequence. At least, probably interactive.
I've intentionally left the denoument flexible -- or, if you like, "undesigned" -- because I didn't think I could construct it without the whole of the game in my subconscious. It's the last whiff of my "implement the first scene first, then the next scene, and so on until the end" plan. I stick to that rule for short games. It would have been impossible for HL, but I am writing the last scene last.
So that's the last task, mostly. Plus I have a few bits of background color to fill in, and the extremely annoying travel bug that I mentioned last time. And there are still 59 "TODO" marks in the source code; I should look through them and (mostly) delete them silently.
I will do some of this work at DragonCon. (What? Travel is good thinking time. I can't convent for a week straight. There'll be a lot of time alone in a hotel room, or wandering around a strange city.)
At the farthest limit, I will have it all wrapped up in the first week of September. I will then pass the complete playable draft around to the beta testers, and start looking at the iOS work.
I will also write another update post at that point. So -- you'll hear from me in less than two weeks. At that point I'll be able to talk more about the process of Shipping The Damn Thing. Strange and scary as that prospect may sound.
