Puzzle 382: Fencing Match 38

Inspired by a construction by Bram de Laat. In this puzzle, all of the 0's and 2's are symmetrically opposite one another, and all of the 1's and 3's are symmetrically opposite one another. (This kind of symmetry would be very easy not to notice; it wouldn't surprise me if a Nikoli puzzle has managed to execute it without my being aware of it. :) )
