I’m looking to make game assets for graphicriver, which would be mostly pixel art. However I don’t use Photoshop for my workflow. My tools can easily export separate images and spritesheets, but they can’t work with PSD files, and I don’t own a Photoshop license.
I’m wondering, how important is it for to provide a nice layered PSD file? Will this affect the sales? Do the end users care? Is it OK to say something like “you can easily import the provided images into Photoshop” on the product page?
