THANK YOU. I got Aseprite and was upset when I exported a .png into unity and it looked like a bug smeared on a window. 12/10 you're the real mvp
lol, thanks for your encouraging comment.
BTW, the PNG you imported into Unity was probably using bilinear sampling and/or was using some form of compression. Unity likes to import textures that way be default which is bad news for us pixel-perfect kind of developers. If you ever find yourself in that situation again check these settings in the texture importer and hit 'Apply':
