I've just made an account on the Visual Novel Database and began a thread in the Perfect Pitch discussion section. In the event that things go south, fans of the series can continue to get in touch with me there.
While I don't want to pretend that Perfect Pitch is safe from harm on itch, keeping my game free to play does work in my favor— because no payment processors are or will be linked to my account, it is less likely that I will be beholden to their policies.
That's a reason to be optimistic for the project page's viability at least in the immediate term. The VNDB communication channel will be utilized as a stop gap solution in the event that I need to pivot platforms and approach to distribution.
