This one would have been hard for a static goal search to find!

Agreed ... static goal search would be in trouble here 
Nice encryption ...

Yes, I'm sure the puzzle would be rated at easy and is targeted more at us newb players. As well apparently as a sort of "anti-bot" example.
It did take me about 3-5 minutes to solve it. With my experience level being 20 some actual games of Arimaa spread out over a couple of years.

I liked it. Goal search would need to identify the goal path, recognize that there are two obstacles, and determine if there is a two-step move that addresses both.

This position looks more like something taken from a real game than something composed. JDB, is the soure of the position a live game?

The position came up in testing the goal detection. I cleaned it up a bit to make it look a little more natural.
Little Puzzle 2:
What is the maximum distance a piece can be from the goal square and still be involved in a four step goal?

5? This is an opposing piece freezing a rabbit that is 4 spaces away and otherwise has a clear run.
But I get the feeling I'm misunderstanding the question.

The gold cat is 7 spaces from the goal and still involved with the four step goal sequence.
Is this what you were looking for?

So the speed of information flow is about double the speed of material transport.
If you've discovered stuff like this in testing, your goal search sounds like it will be almost infallible.
