Hi!
Unfortunately, currently there is no plan on updating this game :(
However, we are using the game for our university project where we create platform where you can play and create visual novels easily: https://uwunovels.com/novel/648605c6e49f1749d2b1a7b9 (sorry. only russian, we didn't add localization system yet...).
You can follow us on discord: https://discord.gg/4UB2j86JNw. Maybe we will focus on english localization and update the game just for you <3
