we gonna increase the price on major updates only (0.X) by a few cents until we reach version 0.9. from there the game will be selling at a fixed price (we plan for around ~20 USD for early-access and around ~40 USD for the full game). after the 0.9 the game will require only one purchase.
whether you would like to pay for these updates or wait for the early-access release is up to you
Thanks for the answers, I cannot afford to support payments for the updates but I look forward to the early access release, one more question, will you switch to Steam like other devs? I hope you stick to itch.io or at least stick to it as an extra option for those that don't want to use Steam, not that I have anything against Steam, I use Steam for adult content often but I prefer itch always, something I noticed is devs end up having a partial release on itch.io and then completely ditch it so the one on itch.io is more of a demo at that point or is no longer being updated like the steam version
we definitely gonna have Steam. as for itch.io - we'd really like to keep it as an alternative, and I hope we will. depends on their policy, as of recently, they haven't been quite friendly to NSFW devs
