These worked fine when they were released years ago. Sorry if this type of font is not supported by Unity any more...

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
They are 16x16 but scaled in demo. Yes you can scale as u like.
Some have attack anumations and some share animations.
You can click on a mob in demo to make it attack, walk or turn. If you hear steps it is walk if you hear attack sound is supposed to be attack animation. But some use the same for all 3.
Thanks. I don't think the mob sprites where ever totally joined like the items were? Maybe each Mob joined with others of the same type? I am not sure it would be easier to use joined either? It might be more efficient but can use TexturePacker or ShoeBox or Unity or Godot to join them into a sprite sheet in a build step anyway to negate that efficience gain... idk
