My personal thoughts on the situation: it's been brought up several times and I agree so far:
Braindrop announces an update -> external circumstances come that make the targeted date impossible -> people get pissed -> BD says it will come at a later date with more content -> external circumstances or an underestimation of scope or other disturbances make the date impossible again -> people get pissed -> BD gets more bogged down and digs the hole in his own writing block cade.
Here's what I think would help him the most:
1. he has to realize that no matter how much he puts out with the next update, there will be quite a few people who say: "We waited decades for that little update now?". Fucking Milker!!!"*
He will never be able to please everyone. That being said, he's not the only dev here who's been getting his panties in an unbelievable twist with the update size.
2. his current update model is obviously not working. I think he should aim for smaller updates (2-3 ingame days) in a 4-5 month period for the next update periods. I don't know his work rate nor the work rate of the people looking for bugs for him, but I think less content with a rhythm that leaves enough air that he can still breathe and buffer time for glitches would do him good and at least bring back some trust from his patreon. Then when he has a working workflow again, then he can adjust the size back up bit by bit.
In the end, devs need to realize that extremely large update are more of a bane than a boon for them and prefer to release smaller updates, especially when they've been so repeatedly screwed over in the course of their work.
