Well gents, I can call Chapter 3 in the bag. Its current title is "Clock." After extensive error-solving, model-making, and alpha-testing, it goes on to the beta testers now. Work on Chapter 4 has already begun, and I'm quickly approaching my halfway point for the entire series.
I've also set a tentative release date. If I keep going at my current pace of one chapter per month, with an extra month set aside for thorough beta-testing and wrapping things up, I should be able to kick this thing out in December. I'm somewhat glad Machine for Pigs got pushed back, because I knew that if I hadn't released this by the time MfP came out, everyone would be far too busy to bother with my silly little custom story!
I also hope to release demo v1.3 sometime this month. I've made the candle puzzle a bit easier to solve since so many people are struggling with that one in particular.
