Yeah, unfortunately Patreon is just about the only way we can accept support at the moment. We set up a Subscribestar but despite providing details and being running for a few months now, they haven't validated our account.
We've been considering a Steam release as well as a higher one-time purchase, but their new murky rules have made it difficult as to what we can release and whether or not the title will be pulled if we put out the updates for it.
It's pretty rough for NSFW devs.
We're still putting out free updates so you'll get the content eventually, and honestly if you want to help support us and don't want to use Patreon, just spreading the word about the game helps a lot. Follow on twitter, join the discord, stuff like that. It's all appreciated! <3
