Twisty Little Passages
I've recently been working with Caravel Games on their new project, Twisty Little Passages. It's an awesome puzzle adventure with each map having monsters to battle, doors to unlock, items to find and only one definite solution!
Each puzzle is presented as a laminated page, so using a dry-tip erasable pen, can be replayed over and over if you can't complete it or just fancy replaying it!
Anyway, they've just launched their kickstarter and I encourage you to check it out: https://www.kickstarter.com/projects/caravelgames/twisty-little-passages
