itch.io

For reference, LLabyrinth has a 4.5/5 star on F95 with 240 comments on the thread. And I would encourage you to look up the thread for this game (yes, they posted V2 there). It has very healthy engagement with people praising your work consistently. 

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).

For discoverability, Patreon is the best platform. In any case, no reason to be on multiple platforms like Patreon + SubscriberStar

I'm sure you have answered this before, but considering recent events with itch.io, should we revisit the idea of a Patreon page? It'll make your work more discoverable.
