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!
We use OG version at our school but will introduce this instead. I try to implement use of foss where possible in my teaching. S little unrelated but very good CAD alternatives to fusion 360 that has a similar “easy” GUI? Blender is ok but not really a CAD tool.
FreeCAD is probably what you’re looking for, it had a bad UI but just released 1.0 recently and is pretty decent now. Also I really recommend checking Pixelorama over libresprite for a FOSS pixel art tool.
