Theoretical
Within week 3 there were no theoretical problems which occurred within the focused development of individual tower defense assets. This is because week 3 targeted upon the production of assets within blender to construct the individual tower & enemy assets. The research following this week was aimed at the tower & enemy limitations & appearance
Practical
When developing the assets within blender, converting the concepts into a simplified mesh matching a voxel art style was a challenge at first to develop. However, following some examples of the assets the tower defense is aiming for presented a clear idea of how the towers & enemies should appear.
