The purpose of this project has been to make a video game capable of entertaining the players while taking back to the essence of the old ’The Legend of Zelda’ games. This was a project done with Unity and implemented in C#. It has been implemented in order to work in computers with the chance of exporting them to android platforms. For this project it was decided to not use the Unity tools regarding colliders in order to optimize the performance of the project and evade, as long as possible, the use of the Update method and the MonoBehaviour objects for the same reasons. This document explains the different methodologies used, the different decisions taken and the problems faced during the whole process. It is the final deliverable of the ’Treball de Final de Master’ for the Master degree in informatics in the University of Lleida.
