There is no next update. There will be a next update on the Patreon. This is only a demo.
actually, saying that there is no update is wrong. Last month Patreon got a housekeeping update, so Itch io didn't have any new updates. In August, we got Lars Day 9. In September, we got Parker Day 9 part 1 and part 2. The public version got no update in October because they received two months' worth of updates in one sitting. In November, we received a reworked Mark Ep 1. And finally, in December, we got Mark day 9 update. Itch io usually has a new update every month. If people read monthly reports on Patreon, they will know that they have a new update once a month
