Agincourt Puzzle

Description

The puzzle contains the full set of 2-, 3-, and 4-ominoes with arrows such that the pieces may be flipped horizontally with the arrows' direction remaining unchanged. The main goal of the puzzle is to make four 4×4 squares with the arrows pointing in the same direction.
18 pieces, plus promo piece, 3/16" transparent colored lasercut acrylic. Designed by Alexandre Muñiz. This is my last copy of the first edition; the second edition has thinner plastic and different colors.
