He sees you when you're sleeping; he knows when you're awake ...
He knows if you've been bad or good.
Played this last night. Had an absolute blast and I would like to put this on my list of games to get. It just has one very big problem. At least half the colors look identical to me.
Usually when this happens in a game I can alter the components a bit. I take a magic marker and mark one set of pieces to distinguish it from another. But that would not work in this case. I had thought of just getting some additional cubes of more varied color but then I would not know how to replace the exclamation point markers.
Use Pennygems. They solve a surprising number of problems for a surprising number of games. My wife backed one of his Kickstarters, and we've not regretted it, yet.
Realistically, you only need one Primary sheet for Concept. $15 plus shipping. You could probably even use a "Quartet Sheet" (https://www.etsy.com/listing/100962501/pennygems-quartet-she...)
If you get some "JumboGems" to go with, you can use those instead of the question marks and/or exclamation point - and then use the matching PennyGems in the same way you'd use the matching cubes.
