Just completed a playthrough of this game. Highlights in the storyline I wrote include: a subplot about an enemy of the Agency that my agent unknowingly had a hand in creating, Stonehenge getting obliterated in a Summer Solstice ritual, trying (and failing) to prevent a murder, and my agent deliberately forcing her way to the ending (which I can tell you it is glorious)
Though I admit I probably made an error with the first entry because I didn't realise the day coincided with a certain date of significance, which would've made the starting prompt a lot harder if I followed it as it is.
Still, I can't praise this game enough if I tried. The concept of time travelling by bouncing around different dates on a planner is such a novel idea. The only downside is that it is ridiculously addictive and requires multiple tools for generating prompts (you'll need both playing cards and tarot cards, whereas in most other games it's either), though this also lends itself to a diverse array of compelling ideas at a level I haven't seen in any other journalling game.
