Hello, I wanted to explain why there is no longer an option to download the demo. 

I had an account on inworld ai plataform where I had my npc, that represents a historical figure, and where I could create an API to connect with Unity. However, I was using the free plan and as there were many users playing the demo, I received a notification about the high traffic on my account and they recommended that I switch to the paid plan. As I decided to continue with the free plan, unfortunately it reached the limit and I can no longer use it, nor can I log into my account that I had created.

Inworld has changed a lot, now it seems like there is no longer a free plan. I tried to contact them to create a new account and also find out the price of the paid plan. Now I'm waiting for their response.

Thank you to everyone who downloaded and played the demo. Unfortunately,  the download remains unavailable due to these server/API limits.  I apologize for the inconvenience.
