Hello! Reading your sweet words made me incredibly happy! 🌸To answer your question, the reason you couldn't find the patch is that the Steam version isn't finished yet!
In the extra story, you'll get to see what happens after the "Don't turn back" route! The story really takes off from there, and the siblings' relationship deepens even more!
As for playing on a Mac: my publisher mentioned that they should be able to release a Mac version on Steam! (Though communication with them can sometimes be a bit unpredictable, so please take it as a tentative plan for now! 💦)
At the same time, I’m also working with a wonderful, trusted translator to release an official English version of the original game (so no patch will be needed!). To make this available for Mac users too, I’m currently looking into setting up a Japanese rental server so you can play it directly in your web browser! Please note that due to server maintenance costs, the browser version will only be available for a limited time.
Thank you so much for following me on Twitter as well! If your account isn't locked/private, I'd love to follow you back! Please feel free to talk to me anytime! 🌸
Thank you for your sweet, caring words! I will make sure to eat well, rest well, and do my absolute best!! 🥰
