I really hope the game isn't abandoned
This page has the latest public version, no new versions are available to the public. My internal version has the first out of 3 or 4 chapters, a big update to live2d models, new characters, new resources, updated interface, all available secondary routes. What is left to do is some more cgi and some refinement of the mini game. A game release of the first chapter should happen eventually, I don't have a date for it. Please subscribe to the patreon, one of the reason of the slow progress is that I need to work on side jobs to get income. I'll be updating the patreon in a few days also
