Very nice action with a good feel and an engaging atmosphere from the music. This would make a fun educational game, especially with the multi-language support. I found one minor problem which is that the pink/purple bar that asks you "What colour is this?" changes the colour of the object underneath. So the green object is not green when the question is asked. This is a minor flaw because it's easy to make a mental note of the colour before you touch the object but that may not be so easy for some players.
