"you bought the game once, as a customer you wish to receive complete features, polished experience and a fully playable mechanics.
The patreon is just an option to give us extra support and donation, in exchange as gratitude we open some early features for the donators.
You buy game on itch once, patreon people pay each month, then at the end of month you just receive updates for free. In terms of funding the game patreon is our only secure tool especially nowadays when all paid NSFW games got deindexed, we barely earn anything from itch io now." -From Development team
To me this makes sense that's why i don't complain about the wait time. To me this is reasonable. Though if you are in the discord. You can see the problems the developer is going through. So it takes more time for updates as they also have to worry about themselves.
