It's neat! Had to bring out excel for a couple of puzzles, got very stuck on 23, but managed to finish in about an hour and a half (I'm slow)
Thank you for the game!
I always love to hear what tools folks used to help them map out the puzzles. I was a post-it note guy during the design phase.
Most of the time for me it was piece of paper, pen and marker x)
Excel was out for 23 and one with two 2x3 colored rectengulars (can't remember which one exactly).
