Okay after playing it for a bit here's my thoughts:
I am extremely happy with the update, can't wait for the paid full release. On a personal note, although I do like that the ass gets bigger in this update compared to last, I do wish it could get even bigger, kinda like how the belly can get absurdly big. A body type customizer would be great too, but I know that'll probably be hard to add. I think we should also be able customize the height of the character. Ngl I'm actually kinda interested in the story (or dialogue) I'm a really big fan, and can't wait to see what the Founder looks like. As for the digestion system, I think it's perfect right now, I think any faster and it wouldn't make the game as fun. I think the shop is a great addition, and it does add some "balance" to the game. Lastly, the walking speed is great and the eating while walking mechanic is a perfect.
Ps: I do think that for the PC version there should be a setting to not use the drag and drop function. However, I would understand if you don't want to add it since you spent a lot of time working on the drag and drop function
My questions:
1) Are you planning to add audio
1.1) If you are planning to add audio, are burps a consideration?
1.2) If you are planning to add audio, (although I know a lot of people aren't into this) would farts also be a consideration?
2) Are you planning to add giggle physics? (Would be pretty cool to see the character giggling around)
3) Is adding a way to feed the other NPCs possible?
3.1) If feeding other NPCs is possible, could feeding the founder and letting them get to an absurd size be possible? (I would assume you would only be able to do this after you get to a certain size yourself)
Overall, I'm really liking your work, keep up the awesome job!!! I'll be waiting for the PC update. Please don't feel rushed, mental health is very important and you should look out for yourself
