Aaaaand, stuck again. This is hopeless.

And this time for good, I'm afraid, since I've been for the whole day.
I'm in the castle which is the next one to the castle with the horrible weight equaling puzzle I've talked about in my previous comment, and I've found a puzzle in which you have to rearrange 4 blocks, in a grid of 4*3 squares. You have hints about how to do it, but I don't understand very well what they mean. I think they're written a little in a "cavespeak" style and, if on top of that, English is not your native language, whis is my case, then you're done for.
The hints are these ones:
STAR UPPER LEFT TO HEART!
SQUARE IS IN LINE WITH HEART!
CIRCLE IS AT BOTTOM FAR FROM STAR
HEART IS NEAR CIRCLE!
And that's all, you're on your own. I've tried all combination possible that (more or less) match the instructions given, but no results so far. Any help will be appreciated, thanks.
Solved. I've found a walkthrough and I've used it. Yeah, I know, it ruins the fun, bla bla bla... But I wasn't interpreting correctly the first hint so I'd never be able to solve it 'cause I was always rearranging the blocks in a wrong way.
