Unity Game Engine first touch

For the past few weeks, I'm not working on the programming whereas I'm spending my time learning Unity Game Engine. The first game I made was a rather simple game where there is a space ship at the bottom of the screen shooting the asteroid coming from the top of the screen. I am quite satisfied with the engine especially on particle system, it makes my life easier when creating the explosion effect. This is not my intention to bring the game to the world since I'm still studying on the game engine, but to get myself familiar with the user interface.

Next I am going to learn to make a Load Runner game, I miss this game when I was still in young. The game development on this time is slightly advance where I am using Orthello, a 2D game framework. Below is my progress for this week, where I have the level design setup.
