Not all directions are included in the asset. It only contains animations for down, right, and right-down. And one animation for running up.
Hello!
The spritesheet actually has two blocks of sprites.
The first one includes all animations for down, down-diagonal, and side. The second block is right below it, separated by a small gap, and contains the opposite directions (up, opposite diagonal, and opposite side).
Since the sprites are quite similar, it can be a bit hard to spot at first glance, especially without a guide.
