Thank you, Sein.
I know I could (sort of) make the upper body of that walk-with-sword-in-hand animation move up and down a little bit, which I think would improve it, but I'm holding back on adding more frames. Doing that with the jump is paradoxical, especially because so little could be reused from one frame to the next... But I'm playing around, and learning more about animation as I do it. That *may* (I guess......) help me when doing the next animations.
Reusing stuff will be key, by the way. Which I'll analyze in the future when I'm optimizing everything and pulling my hair off.
So far I've been analyzing some well animated NES games, and boy, would they reuse their tiles...
By the way, I may have to cut that smear from the first attack animation because of that. I don't think it could be reused anywhere else.
But I'll do more tries, see what works.
