Oooh, very nice!
I'm certainly not the single most experienced solo journaling game player, but I think this is the first one I've seen with a digital component like this.
Thanks, I'm not too well versed in solo games either but I know there are a few others out there with digital components.
I've found that Twine is really handy for TTRPGs and I plan on including digital components to all my future games as play tools.
