Thank you for feedbacks. I forgot to fix seeing reply after changing mail thing :D
Game was much stable before i add saving system. Save system has really annoyed me. I recommend playing it in one go.
Getting saving to work well can be a pain, so I totally understand. Right now the game is short enough that it's completely reasonable to finish it in one go and not worry about saving at all. I honestly found it by accident, as I had needed to stop to do something else the first time I pulled it out to play, and didn't know how long the game was at that point. I played around with a few other things first (mainly the disappearing email reply thing, but also double checking all my notes and searches) before thinking about testing the saving. Even there I think I only thought about it because you mentioned it was a new feature, and I know how easy it can be for bugs to slip through the cracks when adding them. Hopefully you can figure it out without it giving you too much more of a headache.
