- The English version of the Antonio route is now fully uploaded - 19 December 2025
The English version of the Antonio route is now fully uploaded. The story is complete and playable through to the ending.The language is still being refined. This update focuses on improving clarity and tone, and I’ll continue polishing the writing going forward. Since the story is set in a British boarding school, accuracy in language and atmosphere matters to me, and I’d rather keep refining it than treat the current version as final.Since May, this project has been developed as a solo project, and decisions and pacing are handled accordingly.If you previously only played the first one or two chapters, I strongly recommend starting a new playthrough. The game is still in Early Access, and earlier builds were made before the endings were implemented. Loading old saves may result in unexpected bugs or issues with reaching certain endings.The Antonio route contains six final endings and…

- Thank you for walking with us through Early Access. - 24 September 2025
Dear players,We’ve finally completed all endings of the Antonio route.This is the first game I’ve ever made, and I know it’s far from perfect. There are many places that feel immature, many things I wish I could’ve done better. Early Access was never meant to be a finished version — there were always going to be changes along the way.Back in May, when our second producer left the team, I became the sole developer behind this project. That means I haven’t been able to reply to every message, or keep up with every platform, or run proper promotions.But you stayed.You played the EA version, left comments, shared it with friends… You saw something in this story, believed it was worth continuing, and kept waiting. And for that — I’m deeply grateful.To me, EA players are not just “players.” You are the ones who witnessed this story grow, and watched me grow alongside it.🍂 Upcoming Plans: Aut…

It’s every comment, every walkthrough, every fan illustration and piece of merch that reminds me: this world we’re building matters to someone out there.We are still on track to release the full Antonio route on September 12 in Simplified Chinese.
