1. Where can I get the code to unlock game content?
Unlocking codes are available to patrons of at least Supporter tier. Join Wamgame at https://www.patreon.com/Wamgame
2. Can I create my own character?
Not really. You will by able to change some cosmetic details like hair, skin tone and accesories. It is not possible to change the physical look of the characters.
Contact me on Patreon and together we can add the character you want.
The appearance of the characters is tightly tied to the 3D data, and all the physics needed to make the game work depends on those.
3. Is it possible to remove clothing items during the session?
It will be possible to take off some of the coats and flat types of shoes. But for the reasons partially explained above it is not possible to change the 3D data of the characters in-game.
