The most easy task is the hardest

About 6 months ago I dabbed with Unity3d. I made a huge world and had the FPS controller walk around in it. I followed about 80 videos of the BurgZurg series and also watched some space invader tutorial. I have now completely forgot everything.

I refreshed up on the basics of unity and now I am just trying to take a square move across the terrain.

It has taken me almost 3 hours to figure out how to do this. I am making a game similar to the Defend Your Castle game where you just flick stick figures into the air. Does anyone know of a tutorial that will help me with most of these concepts?
