Well I'm still hopeful that next year there will be updates for Fantasy Dating (please don't abandon this game). In the meantime I'll look at this demo of your new game. Do you intend to make them complete for payment, or will you leave them complete for free but with extra paid content?
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.
