If you do not wish to maintain a Patreon on SubscriberStar page, posting the game on pirate forums like F95 would gain you a lot of attraction (with the obvious downside of people not paying for your game if you do decide to sell it). In fact, I discovered your first game only after it was posted on F95. And there will be other people like myself on such forums, who will continue to donate/pay for games despite them being posted there by pirates (mostly because that forum has one of the best search features; so it's really easy to discover new games).
There will also not be any contract/pressure to deliver update on any cadence (since people get it for free).
Yeah I do check from time to time, it's helpful to see if anyone encountered bugs but there isn't much activity unless it's after a recent update. Given the amount of time it takes me to update I don't think a monthly thing is a good idea (I haven't really been paying attention to any recent changes in this area, all I remember is the negativity surrounding it). I would consider a support per update released kind of thing as it would be a way to gauge interest in a project, but itch does not support that since it's more of a storefront.
I'll just continue with the way things are for now, maybe in the future I can be a faster dev. And thanks for the continued support.
