When I worked on the game Mobile Linebacker, I was primarily involved as a programmer. My tasks were to create scripts to be used in the Unity 3D Game engine, and to fix any bugs. I spent a lot of time working with game testers to discover any bugs that might hinder gameplay.
There were times when I was essentially a code editor, reading through all the scripts written to make sure there were no simple syntax errors which would cause problems. I also was involved in running through each level of the game to make sure all the bugs had been found.
Finally, I created a few painted textures for various items in the game.
