Update 0.2

This is the first major update!

Before the game controlled with the A and D keys, with space to fire the cannon.  Now to support mobile-friendly controls I've created a steering wheel for the boat. The player can touch and rotate this wheel to turn the ship. Firing a cannon is now performed by double-tapping the screen.

During play, there is a counter at the top which tracks how far you have travelled. This however needs more work to be more accurate and display on the game over screen.

The camera has been updated so you can now see much further on.

There will be more general fixes coming soon since there is still minor things that need fixing
