My kids, including the 13 year old loved this game!  Its a combination of cooperation and strategy, but not super hard - my six year old keeps bugging me to play again and again :)
One person is in control of the lantern, aka the seeker and everyone else is in charge of the Shadowlings and needs to work together to keep them safe and ultimately get them all to one hiding spot to win the game!   We suggest using at least one more Shadowling than there are players and using less hiding places for longer game play - overall we give the game a 5 out of 5 for fun, ease and laughs!

The game has some set up that needs to be done before play, doesn't take very long but if you have some impatient types, its nice to know!  I also suggest having a small flashlight if you are playing with younger ones, it can be difficult for them to see the Shadowlings when it is time for them to move!  The instruction booklet is well laid out and the rules are simple and easy.  If you are more of a visual learner, I liked this video from Geek & Sundry -
