Per the dev log from yesterday, 30 January 2021:
"[DevLog] Quick Update - Optimization!
Hello Everyone!
Sorry! Because of some problems in my life it affected the progress of the new build, but now that everything is fine again, I was able to update more often on progress.
Dungeon 3 was really a new challenge for me as it is larger and more complicated than the dungeons that came out before.
Dungeon 3 main contents!?
- Design areas are larger and more detailed.
- Unlike the previous 2 dungeons you just need to go from point A to B to complete. In new dungeon you need to go back and forth through the areas many times to solve puzzles and unlock to other areas, more puzzles.
- Dungeon 3 will have more H scenes, you can H with female enemies after they are defeated.
- Separate underwater weapon system.
- New monster enemies.
More work, bigger dungeon so I'm having optimization problems. I have found a fix but it is taking more time, now I'm fixing each of the things in the new dungeon to make it work better. Really sorry for longer
I will work higher performance to make up for last year! New updates will be coming soon!"

The dev mentioned that there's been some life problems recently that they have had to deal with. They elaborated more in a comment under a post from a few weeks ago, mentioning that they had to be hospitalized again this month due to various issues (IIRC they mentioned before they have a heart condition/disease, so that might be the causative factor). So, trying to get the optimization done of a new area that's claimed to be many times larger than any of the previous content drops, doing it by themselves, and in addition to the persistent health problems has caused a lot of issues.
From what I've seen, most patrons are understanding. However, there are still calls for the dev to be more vocal and transparent with what's going on, considering they have only been providing minor updates every couple weeks.
Anyways, I'll be sure to share the new build whenever it comes available, unless someone else who's still also a supporter beats me to it.
Hopefully soon.
