Challenge 3 will get you to use diagonal direction keys to move to the different islands in order and then to the lighthouse. Now you have a choice of cutting across the water by using the diagonal direction keys.
Which is going to be the fastest way to get to the next island?
Does having more direction keys to choose from make it easier?
Can you choose a different colour for the pen each time you visit a new island?
Once completed, press on the button ‘try another’. This will take you to Challenge 4.
