Yes, except in that discord post he said that all renders were finished and he just had some dialogue and sound effects to complete. And considering the writing in this game, I don't think writer's block was an issue for Hot Tomato, quite the opposite actually.
We also know that this wasn't bullshit and that the update was nearly done based on what Ruykiru eventually released.
Hot Tomato posted 28 times on Subscribestar between July and September 2024, representing very heavy engagement with subscribers and including a bunch of teaser posts for the update in the final week of September. This doesn't support the idea he was contemplating abandonment.
His final Subscribestar post was Sep 25 and his final discord message was the same day.
I think it is perfectly valid to speculate on the abandonment of this game when there are people such as yourself who directly accuse the dev of lacking "decency". Given the available evidence, this is one of the few times where I'm convinced that negative life events are a very real possibility.
