I'll like to release a 0.1 with at least 1 hour of playabilityIt depends. Are you doing a 0.1 as fast as possible because you want to rake in the patreon cash? How much content does your 0.1 game has? Are you worried about telling a compelling story, making a fun game first or are you worried more about how much money can you get from people?
Some devs seems to think of h-games as a popularity thing, especially western ones. They try to test the waters with whatever is more popular and then as soon as their game has gotten a little bit of attention they start to stall the development, getting as much money as possible before finishing. People here are starting to get a little more aware and generally, posting a 0.1 with no content gives off the vibe that you just want some money as soon as possible. It's not wrong to post a 0.1 but ask yourself if you really want to make a game and get money for it or if you just want money with "I'm making a game!" being just a front.
Then put your game up anyway and do at least some updates before officially opening a patreon. This will be good for you since you will be able to see if you're able to actually push out new releases in a somewhat consistent basis. A lot of people venture into gamedev but after seeing the hardships of having to work on your game often and not just when they "feel like doing it" quit.I'll like to release a 0.1 with at least 1 hour of playability
Im just concern about the fact than i could not consider myself legitimate enough to have a patreon with just one 0.1 version
