An idea for how to save and restore the state of an InklewriterSharp game.

InklewriterSharpSaveRestore.cs

// Load story file
string storyJson = File.ReadAllText ("Stories/musgraveritual.json");
StoryModel model = StoryModel.Create (storyJson);

// Find the saved stitch and fast forward the story's initial stitch:
string restoredStitchName = "holmesResumedHis"; // load this from disk
foreach (var stitch in model.Story.Stitches) {
    if (stitch.Name == restoredStitchName) {
        // Fast forward the story to this stitch
        model.Story.InitialStitch = stitch;
        break;
    }
}

// Load story into player
StoryPlayer player = new StoryPlayer (model, new Inklewriter.MarkupConverters.ConsoleMarkupConverter ());

// Collect all saved flag strings
List<string> restoredFlagStrings = new List<string> { "a:1", "b:2", "c:3" }; // load this from disk
List<FlagValue> flags = new List<FlagValue>();
foreach (var flag in restoredFlagStrings)
{
    // TODO Convert flag strings into FlagValue objects. There's not a clean API for this,
    // but some code from StoryModel.ProcessFlagSettings could be recycled.
}

// Create our first Chunk using the InitialStitch that we previously set,
// and restore all of its saved flags.
player.CreateFirstChunkWithFlags(flags);
