I think the gap between patreon and public version should be a bit longer. Like, it'd be less likely for people to pay for early access when they can just wait a week instead.

I dont know if it would make much of a difference, i personally dont use Patreon or other similar sites, id rather pay full price for the game once its finished.
Might change my mind at some point since i do want to support Ncrow but when it comes to waiting its not an issue since i already am waiting for so many other games that take much longer to update.
I believe Ncrow is one of the better/best Devs since they deliver great quality and does it often which i believe is the biggest reason why ppl would turn to support them.
But i dunnu im just a silly goose.
