Thank you for kind words!
1) It depends what you mean by reworking. If what you had in mind are some touchups to already released scenes through minor rewrites, filling missing gaps, adding callbacks to optional events, brand new optional scenes, implementation of missing art assets like sprites and cgs, then yeah. But we are not planning to restart any of the routes from the start or anything like that
2) Of course it will be. Honoka, Naomi and Aida will receive new scenes and their routes are intended to be completed in a similar manner Shiori's, Alice's and Akira's are. Similarly with Okisho's and Natsuko's side routes, Keisuke's stories and Daichi's side route which are also in active development
3) It feels flattering you ask but for now we are not asking players for financial support. I hope it won't sound wrong, but we feel financial responsibility would be a great burden, and we prefer the game to be out of pocket instead of crowdfunding it or asking for donations. That being said, our Discord server has shill-space channel with Ko-fi's setted up by individual team members for anyone who wants to support their efforts
