You can try our Christmas themed game here Snowball Splat
Runs best on an iPad.
This is based on the Splat Medusa game devised by iMuse for the 2013 Ure Discovery project. This incorporated two dozen depictions of the head of Medusa created by 16 year olds from a special school.
These are simple, text-free games that can be enjoyed by all age groups and abilities. The idea came from http://creativejs.com/tutorials/create-an-ipad-optimised-game/
Merry Christmas and Happy New Year 2014!
