Oh yeah I followed Limit Theory very closely, we were all distraught when he vanished. I always complain about Alex's working pace (Sorry, Alex!!!) but we have it good compared to the people of LT. Sucks what happened there.
Fortunately he is back on track with a new workflow. The main changes being: No daily dev-log never ever again, and a workplace out of his house.
You can also check the DSS team duo method: monthly updates. Great? Well for the past few months the coding side of the updates have been exactly this: "I coded some stuff that will be useful to the game but it's boring to talk about. Now onto the graphics..." It's indeed not interesting and time costly. You can also check how Megasphere's dev did a couple of 8h streams of himself working on the game. And surprise, it's BORING, because those things takes a awful lot of time to get together. There is no magic button that makes everything works in a snap and as he show, you can take 2 days to make 2D door opening (in this case a very cool door though). Even a small team as the one on Kerbal Space Program (6 people on the dev side) need to have a CM in charge of collecting and formatting weekly reports, and they did said at some point that it was taking them often an hour each to write those, each week. That's 6 man-hour of work lost each week, as if one person never showed up on Fridays.
I understand why people want more updates, but frankly past a certain point in the development cycle it's a burden for small teams, does nothing but slow down the process, and is but an endless stream of "today I squashed some bugs" bullet points anyway (like RimWorld's devlogs). Given Alex is active on the forum 7/7, I'd say that's an indication enough that he is still working on the game.
