Saves do work, but with every update the dev adds / modifies text in the scripts (so characters say something differently or additionally from the previous version). Sometimes that also includes adding / modifying variables. I save multiple times with every update, at least once per scene. That way, if one save won't load properly, I load the save just before that.
I keep backing up one save at a time until I get one that works. I don't normally have to try more than two or three saves max before one will load for me; sometimes the very first one I use works. Usually what loads is a bit earlier in the scene than when I previously saved (often at the beginning of the scene). For example, when loading one of my previous saves with v0.6.3 (see my attached save since you requested one), I had saved at a choice menu dealing with Mrs. Johnson. Rather than loading at that choice, the latest update of the game loaded at the start of the scene.
Still, it doesn't require much replaying at all, so it's not too bad. Just save relatively often (you have unlimited pages of saves, so no real reason to avoid it) and you shouldn't have much trouble in the future with the game.
