are they topdown/ they can move left right up and down?
Each have one direction which can be used as two by scaling x by -1 which flips it. And compatible with 4 way by additionally using down as right and up as left. Like angband :)
The PixelHero https://henrysoftware.itch.io/godot-pixel-hero does have four complete directional walk animatios. But attack is just a punch or kick for now
