I know I haven't submitted anything. Life got in the way and I have to leave the jam. I might finish this eventually as some kind of asset pack, but for now the few animations I was able to finish when I still had time to work on them.
Again, might make a more complete pack to avenge the time lost.
I can vouch for Aseprite, it's low probably the most low-impact thing I've used for pixel art short of MSPaint. It's not as hard to understand as you would think, but you will certainly want to explore the UI and learn its hotkeys. Libresprite is basically a Free Open-Source fork of an older version of Aseprite, but it does what it needs to do.
dustdfg brought up Pixelorama and I can also vouch for that program, it's just a bit heavier in performance and I've had issues from leaving it running in the background for a while. It's really close to Aseprite in features and UI: also it's free and you can run it in a browser if you just wanna try it out.
I can't say that I really liked the portrait I drew yesterday, so I remade it by drawing by hand instead of mechanically trying to find the exact pixels I wanted. I then added some expressions with a few more to be drawn.
