At episode 23 right now but damn! not only the game has the sync issues I mentioned earlier (the same Hourglass movie will play fine for a while but always ends desyncing at some point or another). Hourglass also refuses to record audio when generating an AVI, it seems, which kinda sucks since music is a nice part of the game.
Not only the audio is an issue when generating an AVI; the game has this weird behavior where, while recording/playing a movie, at the end of all levels that you complete by flying off the screen (episodes X, XX and, I suppose the same will happen in XXIX), Hourglass will "hang" for about ~40 seconds before the game resumes its normal rate but when creating an AVI, at that point Hourglass hangs ~40 seconds at each frame!. Damn! It's like the game doesn't want to be TASed!. I just spent nearly 3 hours waiting for encoding of the last few frames of episode X.
I'm posting here the resulting AVI displaying the first 10 episodes of the game. Keep in mind that the first levels are sloppy as I still wasn't familiar or comfortable with Hourglass' savestates and frame-stepping. Also there's little chance to do interesting things in the first levels, it's only in later levels, after time travel and time stopping are introduced, that a better understanding of Hourglass allows to do some interesting things in a TAS that are not possible otherwise (who'd think that you can complete episode XVIII using only 3 time travels?).
I'm starting to think that it might be impossible to get a proper, acceptable for inclusion, WFT file for this game.
Anyway, I'm posting the first 10 episodes WIP to hear your opinion. I suggest you play this video at 2x or 4x.
