Definitely giving this a go, thanks for sharing!
One thing that tripped me up was the name. I use Sketch[1] quite a lot and the reason I clicked the headline was I immediately though maybe this was something new around implementing design systems using Sketch. This tool is much more interesting to me, but still, thought I should mention it.
Loving the simplicity of the design in this little tool. It'll be interesting to see whether it works beyond simple experiences. The syntax makes me think it ought to be composable, like having larger state charts composed of smaller components, pluggable via open ended transitions either by omitting the target state or having some special syntax saying "plug in your state here".
Anyway, definitely going to give this a go, looks great!
