l usually don't play adventure games because l don't like random clicking, but l played (and finished) this one because it had a stone age theme, which is a good idea and because everything makes sense...everything you click either moves (butterflies, insects etc.) or interacts with you, killing you or making you advance on the stage..l must say, the game wasn't very hard but it was very enjoyable...l hope you make a sequel with Sam now being in the medieval era...
