I think you must have been the very first Indonesian VN creator I've met. I haven't really played the first Nusantara since this is the first one that I found, but I gotta say I'm already interested. Even if it's still in progress, everything about it is already interesting. Love the UI design and characters, and I'm pretty much curious about the story. I really would love to support you when I can. Wish you luck!
Speaking of which, is there really Jalan Hakim in Jakarta? If so, I haven't found it let alone been there eheh
