Hi! I'm sorry to hear you feel that way, and I understand your frustration about not having access to the Halloween update yet. However, given the amount of hours (dozens...) I put into each update, especially this latest Halloween Update, it wouldn't make sense for me not to have a period where it's exclusively available to paid Patreon members. This isn't my full-time job - every hour not spent on my real 9-5 job or school, I'm spending working on this game. The way I can sustain putting that many hours into My Fluffy Neighbor is through the support of Patreon members, which is why giving them rewards like early access makes sense. Otherwise, the number of people willing to support on Patreon would drop significantly.
I understand your frustration and your request to pay a finalized price for the game. The best option I can offer if you prefer is to pay for a year-long Patreon subscription, which is discounted compared to paying monthly. This will give you access to everything for the entire year if you'd rather pay one time! That option is available through Patreon :)
Again, sorry to hear you feel that way, and I hope this response helps put into perspective why I need to make certain choices with the release schedule.
