This was my first experience using Unity, rather than our in house tech that we had used for previous projects. It was certainly a learning experience, as I was far more used to getting stuck in with lower level problems, while Unity allowed me to worry mostly about far different issues.
One of my tasks in this game was to implement the UI system. However, unlike previous games, there wasn't an easy UI solution at the time, so instead we made use of far more 3D UI elements than we ever could before. Connected with this, I also worked on the input handling, and how that controlled the character.
