Years ago, I tackled a project of creating walking animations for all the major characters of
Phantasy Star III. It took quite a long time to rip all the sprites from the game and even more to reassemble them in an animation that closely mimicked their gaming timing, but I eventually finished them all. This animation of Miun walking left was a result of that project.
In the game, Miun actually reuses Mieu's sprites exactly. At the request of another fan, I altered the look slightly to give Miun a more distinct look here. The hair color is a little bit darker.
