You could join the discord and offer your help there. Also on patreon you can always unsubscribe whenever you want.
Discord? I assume you mean it as where to go to provide feedback and gameplay support, isn't it?
As for Patreon, I was often skeptical over it, not knowing it's functions and perhaps the tiers differing to how much I have, versus how much they cost.
I was looking for the best place that I know - if not guarantees that the majority of the money I will provide, as of now and any other time I'm capable of offering it, will go to the dev-team as this is an independent work.
As for the feedback I want to provide.. honestly, it's a case of documentation. So much stuff is shared across videos, links & comments I'd been having a bad-habit of screenshotting them all to potentially compile them all. same for gameplay Like did you know if you press `Alt + F` you can make your camera have a more focused beam? Stuff like that is barely spoken but could be helpful and would remove frustrations from people who might be too scared or unsure if they'd like this game.
That - and there's far too much people relying on thumbnail spoilers and I feel it must be toned down a smidge for the Dev's shake perhaps.
There is an official discord server for the game. The link to it is on the main page.
About Patreon, everything is quite simple: the developer writes under each tier what exactly you will receive as a thank you for donating a given amount. If you just want to support the developer, without pursuing the goal of receiving something in return, then you do not need to worry about the amount - you can specify any amount there that you can donate. The funds are not written off immediately, but at the beginning of the next month, if I remember correctly (I haven't used Patreon for a long time and may be wrong).
And yes, I know about Alt+F
