I saw it posted on reddit about a month ago, but have been unable to track it down. The redditor didn't have a name for it, just called it a WIP pixel art pack. All I have are the 4 pictures they posted.
Ah yes, my apologies for not explicitly stating that I have attempted to use google in my original post. Would you like me to list the rest of my methodology for trying to track this down over the past month? Or shall we assume I've already tried the more obvious avenues of research?
