You're completely right that blob content at home is currently lacklustre. I know it was one of the main selling points of the Jobs & Home update, and likely why it was picked in the poll… but I probably spent far too much time on the portraits and OnlyFats instead!
Before I start work on the Sex update, I want to release a mini update that'll address this. Your ideas are great, and I'd love to add a bunch of new home upgrades targeting characters at the immobile+ stages, especially blobs. You'll be able to progress through the full blob milestones, and hopefully it'll be fun to do so.
I really like how the livestreaming turned out, so you'll definitely be seeing more of that soon, including for blobs.
Health issues will also be expanded in the mini update. Home doctor visits are a great idea. I'll include that.
I want home upgrades to be an evergreen feature, with new upgrades being added over time. It makes sense to have some sex-related upgrades, and I'd be happy to add BDSM equipment.
Someone else suggested linking binge-eating OF videos to the existing binge-eating minigames, with performance affecting the video's success. I'd love to do that for the sex videos too, so expect to see the new sex mechanics used there.
Thank you for playing my game & hopefully I can keep it growing for a long time to come!
