Just to explain further, I am a 'hobby coder' and am intrigued by HoA as a possible rule set for a basic turn-based RPG game. Similarly, when creating an early alpha, it would be useful to have a pre-established adventure to follow so as not to have to worry about that aspect of design while coding and testing systems. Many table-top RPG designers may freely release mechanics, few release settings and original IP.
Do you have a Patreon or Ko-Fi etc.?
Lastly, your artwork is nicer than many paid products. Quite surprising for a free product.
Thanks for all your efforts and generosity.
