Great to hear you had fun playing. FYI, Fantasy Dating is on hold indefinitely.
I have another project called Ménage à Moi which has a demo available now, and an update is planned to release by the end of November.
I just posted a devlog explaining the status of Fantasy Dating. Unfortunately, it won't be getting an update/rework any time soon.
To answer your question, I went with the early access model. The highest tiers on my Patreon and SubscribeStar pages can play 4 weeks before the public version. And the same applies to the paid itch.io version.
Well at least you won't abandon Fantasy Dating (seriously I really liked this game as you can see lol, mainly because the main character is a futa and can do things with fantasy beings, besides that if I didn't get it wrong in the end it would be possible to have more than one partner/partner and get her pregnant, which is something I really enjoy in games). So does that mean that your games on both Patreon and Itch.io are paid for 4 hours and then released to the public? Thanks for answering me.
The highest tier and itch.io paid release is up to 4 weeks (28 days) before the public release. Other lower cost tiers vary by a week (3 weeks for the next tier down, then 2, then 1). And while the itch.io version is $3 cheaper than the highest tier, that tier has other benefits such as Behind The Scenes posts.
