That's one of the reasons why I stopped supporting this game. I realized that I've supported enough, I realized that my support isn't being valued enough, and I realized that I better put it towards smaller devs who need it more.
That's just how it goes. That warm and fuzzy feeling I mentioned where you feel like an integral component of a project isn't as compelling the larger and larger a project gets. There's absolutely nothing wrong with spreading the love around, especially to up-and-coming creators.
That said, it's hard to add value to your tiers when you want to avoid perks that eat into development time or dictate story content. Instead, we've been fortunate enough to sustain ourselves with a "if you like us, support us" model with very few frills. Sometimes that means people spending $50 an update cycle, other times that means people like you who support us for months and then move on, and sometimes it's people that have stuck around with us for 4+ years. All types have enabled us to consistently work on Pale Carnations and (freely) put it in the hands of everyone.
I really do appreciate the support you've given us in the past and it's your prerogative to say what's enough. I mean, I myself am not a total fan of how centralized the Patreon platform is for this hobby both on the creator and a consumer side, but I won't get into that.
