Katana Zero has almost nothing in common with Sanabi, but I would recommend Sanabi in general if you want more well-crafted narratives and surprisingly expressive pixel characters.

Surprisingly controversial, nowadays.

Is there a tech demo example, just to help people familiarize themselves with what's possible in the tool?

I'm learning how to do pixel art, and I was curious, what was the thought behind the central orange section being bordered by light light orange?

I love the 2nd one!
