Can these " supporters " stop acting like holy knights with a moral ground? I'm pretty sure you're aware you're on a pirate website that has a sole purpose is to give games like this the attention that it needs ( if it's actually good ) and deserves it.
Leaking it once or twice wouldn't be such a detriment to the author ( knowing it happened here before ) because people who are interested in supporting it wouldn't stop regardless knowing they help the artist create an art that they do like.
It will bring new people to try and support the artist whether it would be monthly or whenever it releases hence why i dont really understand the people who supposedly " supported " inatari thinks that leaks are always such a bad thing.
Leaking for the first day or a few days if there are ( levels/tiers to the patreon artist would definitely destroy the game for the artist, but a week or two of waiting while these " supporters " talk about moral ground on how its so wrong to share the game to the public is so off to me. ( You either leak it or you don't, you dont have to post about it acting as if your intention is to help the artist nobody wants/needs to hear it.)
TLDR: If the game is good enough to be recognized it will succeed regardless of the setbacks it has which you guys call it " leaks " Only reason why people are mad is how long public release takes ( 1month? ) which brings people to play the game one time and completely drop it until the next update comes which doesn't really help the artist as the people of the public leading towards losing interest or and wont be new supporters.
quite the ramble, not sure why you needed to create a brand new account to say it though. Inatari sets the public release time, from his perspective the game leaking before that will be detrimental to him and his income, which is something only he will know the specifics of. perhaps he will change it one day, or perhaps not.
Im also not sure about your last point either, the 4.8 changelog post had more likes than any post he's made (on patreon at least), and the average number of likes the posts get has increased a ton the past few updates, meaning the games popularity is really increasing, even with the free release taking a month.
if people are interested enough they'll buy into it, if not there's plenty more to do in life as you wait for your turn when its out for free ¯\_(ツ)_/¯
