etoy issues/making games and mazes

I've downloaded the expamples below too.
But I'm not able to learn scripting from the samples in reasonable time.
I mean, I can imagine that
      color (...)
      sees (...)
~~ false
ifTrue [doAnything]
ifFalse[doAnything else]
has something to do with the observed car's behaviour, but from that lines of code I even can't find out the scripting language basics (except the use of paranthesis and self, which is rather intuitive).

 I painfully missing a reference, a manual or a tutorial about the basic steps. I think that all the painting stuff is rather intuitive, but scripting can't be intuitive, I mean at least you have to know the key words.

When I first found squeakland, I had the idea, that this could be very useful in two ways: 
- Intuitive creating projects focused on interactive learning, from first writing to speech support of handicapped pupils (my wife teaches in such a school)
- Guided introduction in programming environments for children

Does anybody share my problems?
And much more important, has anybody an idea how get further?
