    Interesting puzzle type. While there’s a bit of a feel of things like Nurikabe and Fillomino, it’s got a unique style to it. It probably helped that I was a little paranoid and didn’t go down any blind alleys, but that also meant I was pretty slow.

    Great new genre. I can only echo the comments of other people that this has good potential for wonderful puzzles.
