Thanks for the kind words. This is very much a demo currently, so I'd like to add more features based on user feedback.
Persistent abilities for characters are already implemented, just not for body changes, so this can definitely be added to the skill tree.
Can you expand on what you're envisaging with character interaction? Currently, every period (advance time), each character decides to either undertake one of about 25 solo or 12 pair activities, and this is recorded in their activity history and is remembered by characters when they interact with you. Are you imagining a fully fleshed out AI narration for each pair and period? That would be too computationally expensive to do with an LLM. I could, however, flesh out the nature of the interaction with some tags and modular descriptors that can be assigned based on the character's stats and gamestate.
For phone--I'm focused on building out the base game first, but I'll add phone-friendly UI later.
