The current prototype of the game isn't quite in the state where it's ready for showtime as a widespread public demo IMO, so at the moment the current playable build is exclusive to Patreon.  It mostly serves as a demonstration of the exploration and dialogue system. 

Here's a quick outline of some of the things we plan to add over the next 2-3 months in coming updates as we prepare for the "full" demo launch. 

1. About 10 more NPC conversations/scenes, including some of the characters you can see in the current build but not speak with yet. 

2. Character and Inventory UI (Allowing the player to customize their 'default' body form as well as see the items they possess) 

3. Room Decorating and customization system. (Luckily it's nearly complete but it was made in a separate project from the current build so they need to be combined and integrated. 
4. Save/load system

5. Gallery Interface

6. Combat Minigame
