I haven't fully sorted out the support side of things yet. My original plan was to use SubscribeStar, but getting approved as a new creator has been difficult, and so far I haven't received any response from them. At the moment, Boosty seems like the most likely option, but nothing is final yet.
As for the next update, I don't have an estimated release date yet. After releasing the demo, I took a short break and focused on fixing smaller bugs. Development is now back in full swing, and I'll publish a devlog with more details at the beginning of next month. Hopefully, I'll have a clearer timeline by then.
