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!
From a pure usability and features standpoint, if you are capable of compiling it, there is no reason to use Libresprite over aseprite.
LibreSprite’s only advantage is the GPL license and the ease of installation compared to compiling aseprite (if one does not pay)
