One tiny problem
There seems to be a bug in this game and it prevented me from finishing on my first go at it. At the part when you toss your family across to the other part of the land where the dead mammoth is. Well after I tossed them over I noticed I could click that spot again so I did. What happened was the family cameback, well more like doubled. Suddenly I had a family behind me and then on the other side where they should be. After that happened I couldn't click anything.
But nice game, just try and fix that.
