Hello! Sorry for the confusion and glad that it cleared up for you. Just as an additional info, here is our reply to previous question regarding running on Linux: https://itch.io/t/692620/linux-help-mannequin
Using the itch.io desktop app is always the preferred way, though, since there is no self-updater built into Mannequin and we rely on itch.io platform (and Steam, when the corresponding version releases there) for managing updates.
Wonderful character there! Hopefully you'll find our 'Advanced' color option useful too; it will surely add more flexibility to match your entire game / artwork color style!
