My thoughts on that in particular, I feel like the extra images that he is trying to use is as a learning curve to pick the art work, cause we all know his art partner left the project and he has to pick that up.
So what I want to believe on why the content is very short, is he is using the extra non-canon images in the new app to learn and get better at prompting the art. And less time to slam more content.
Just gonna put some hope that within the duration to develop 0.5 he gets better and used to doing the art and have more time to do more content.
I don't sub so I don't have any info other than things ppl post here about the dev update and so on. And I'm lowkey playing the game for free, no complaints from me aside being considerate towards devs.
