The game looks promising enough as it is rly
Unfortunately patreon is banned in my country and if you ask me there's not that much to do around without the AI feature (obv, lol)
I hope you do look into KoboldAI as it's greatly optimized and can absolutely be an offline/free alternative to ChatGPT. Running those on my own hardware is the only thing available for me so you can trust me on that xD
