My kids have loved playing Samorost 2 and Questionaut lately. Both games involve lots of thinking and problem solving. In a quest to find more games i've come across Little Wheel which I am playing around with at the moment to see if it is suitable to play in the classroom. So far i'm loving it and the main character Little Wheel is very cute. Reminiscent of Wall-e!
Head along and have a play - see what you think!
