The creators said on twitter or patreon that the next update for patreon payers will be late/mid April and late may for non patreon
Tip for any game that you have to wait for patreon tiers before it comes public. Some devs update on other sites same time as first tier gets access to the game. Just type in (adult game “game’s name”) in your search engine. To find what sites the dev updates there game on. Note some p2p are free on these well known sites
