Well, since you just started a week ago, it looks quite good.
so, which engine did you used ? Do you really had to program something or was it just more something like a construction kit, where you just have to pic some stuff and put it together ?

If you have programmed something, it is quite impressive for just a week, but i think you should stay on it and learn some years, then you could become a relative good programmer.

But at least, you should try to use some more interesting textures and change the fonts a bit, to make it more comfortable for our eyes ;D
