I get what you're saying but what I'm asking for is very close to standard practice for most engines that use pixel art and is just generally the easiest way to work with this kind of art while maintaining proper alignment when switching between different animations and maintaining the artist's original intent. Almost every single "pixel art" asset on this website does it in the way I'm asking for. So it's not really out of the ordinary.
You surely know what an "animated flip book" is correct? That's what I want in digital form basically. It's by far the easiest way use pixel art in GameMaker Studio or Godot.
Yes, you can sort of accomplish this by using Photoshop but it's a giant pain in the ass and your animations could still be off slightly (I'm not the original artist!).
Asking for the animations in a form that maintains alignment (i.e. has a proper anchor point, in other words, the corner of the image!) is not a big ask given that it's been 3 years since this thing was released.
Moot point given that I've moved on but if you ever do fix my issue I'll update my review accordingly...
