Rectifying issues in testing

Based on the feedback I received from testers, I had to make some changes to the lake scene. I created cube barriers around all the walls of the terrain so the user can no longer fall (or jump) over the edge. I initially tried to use planes, but there are some fall-through issues with these, so cubes were a better option.

I took on board the feedback about the sparsity of the scene, and did some experiments with the default tree in Unity. However, because the scene was not done to scale, it was difficult to get the tree looking realistic next to the hills and objects, so I decided to leave it out.

An average-sized tree, dwarfing everything in sight.

I also changed the music to something more appropriate; I am using Christy Moore's Ride On, which is Irish-sounding without being too cheesey. I may have to change this based on copyright issues. I then included player instructions on the splash screen.

I think I now have the Unity part of things totally completed. Yay! It's just a case of fixing up the website.
