Noticed this in my distro’s repo today (fedora) and figured I’d bring some attention to it. Asesprite is the premier pixel art tool, so it’s awesome to see someone keeping the FOSS version alive!
There’s also a great book from NoStarchPress made for Asesprite, and assumes absolutely no previous artistic knowledge!
I think Pixelorama (I’m on mobile right now so don’t want to drag up a link) is also FOSS and has a more comparable feature set.
