No plans for an android version for now, I don't have the license to export to android. I'll also probably need to rework the UI to make the game work on a phone screen, and I'd rather focus on a single PC version rather than two separate versions.
Regarding the size and clothes, it's planned, but making sprites take time. If I add bigger sizes right now, I'll need to make more sprites for the outfits and adding clothes will take me more time. For now, I'll prioritize making a few clothes for the sizes that are already available, and once I'm satisfied with the choice of clothes I'll start increasing the maximum size little by little.
And finally, for now Emma is the only one that can visit. Keep in mind this is a work in progress, it still lacks a lot of content.
