Its an interesting concept
But I really struggled to get started
it is never defined in game or in the page what makes a good path, I had to come down to the comments and see if someone else had the same issue which isn't quite nice .
I'd like to see how this would look like expanded on and maybe given a better goal on what to create, maybe with different layouts and such.
Overall its quite nice to watch how the level plays out after you set it up.
Good job!
