Hey Helena!
The main story of AHITR is still on going right now! Each character has their own story too, on top of a bunch of side content.
If you were to hop in right now (and an average reading speed) you're looking at around 30-35 hours of content.
Completely understandable if you'd prefer waiting until everything is rounded off. Right now 8.0.6 is its Alpha phase over on Patreon. Our release schedule is the following:
The Alpha build of a new version is released at the start of each month. About a week later the Beta build is released. Then after another week the Early Access version is released. Then about a month later this version goes free and public. This is our Patreon schedule, it lands here on Itch a bit later due to how adult games are now handled here.
Hopefully this info was helpful and if you have any questions, feel free to poke me!
