Question: You are playing a game on the following 4x4 grid. Each turn you can slide **all** the orange balls into one of four directions: left, up, right or down. A ball will continue sliding along a direction until it hits a wall (solid blue squares), boundary of the grid or another ball. All the balls move at once. Walls do not move. Can you get the balls to finish on the target (T) cells?

I have a completely different solution, the same length as the [other](https://puzzling.stackexchange.com/a/115301/79147) [two](https://puzzling.stackexchange.com/a/115298/79147) at time of posting - still 15 moves. I am wondering if there is a way to solve this in less than 15 moves.

After the first five moves, the grid looks like this:

After the next three, it looks like this:

And the final four moves complete it:
