TL;DR: A Dragon's Treasure will now be released on July 27th instead of June 22nd. Man And Elf's release remains unchanged.
Unfortunately it looks like ADT won't be ready by June 22nd. No, it's nothing to do with covid. There are no problems with the development either, and I do not believe the release will be pushed back a second time. June 22nd was just a bit too optimistic of a timeframe.
The main reason for the delay is that I wound up spending significantly longer on version 1.07 of the original Sable's Grimoire than planned, which pushed development on the sequels back.
What was supposed to be a quick playthrough, taking notes and checking for consistency with the sequels, resulted in a number of text changes, new backgrounds, a couple of sprite fixes, and a variety of other changes. You can see the release notes in the announcements of Sable's Grimoire for more information.
Since that ate up a month of development time which was supposed to be spent on the sequels, I had the choice to either delay one of the sequels and release the other on time, or to delay both.
Man And Elf has already been delayed once, and it was closer to completion than A Dragon's Treasure, so I've chosen to focus on MAE's release and to delay ADT.
Man And Elf is pretty much done. The time between now and release will be used for additional testing, proofreading and editing. The game itself and the OST have both passed review on Steam. The 18+ DLC is currently being reviewed. So I think it's safe to lock MAE in with its current release date.
A Dragon's Treasure is close, but still has a little more work to go. A few more CGs are needed. The updated GUI is still a work in progress. The script shouldn't need many additions or changes, but we'll see when testing time rolls around.
Delays suck, I know. But spending that extra time on the original was worthwhile. It resulted in a number of changes being made to both MAE and ADT to better match the original, with consistency between the three being a big concern, and has hopefully reduced the likelihood of post-release fixes being needed for the sequels.
Here's hoping the next announcement will be something a bit more exciting.
