This should probably be advertised more as renderer than editor as editor without save feature sounds like a joke - why would you create/edit anything if you can't save it?
This comment is less helpful than the one you replied to.
@Simpliplant has a good point, people expect digital paint tools to save, but also made a blanket unqualified statement about creating anything without saving.
@kgwxd replied that some people don't want to save, the blanket statement doesn't apply to everyone. And that's absolutely true. This is a valid, though somewhat tangential, point of view about performance art.
There is a long history of artists using art tools that don't have save or undo. Traditional arts are still founded on this concept, the art world still largely values techniques that involve the risk of screwing it up, and are hard to copy. That's changing over time, digital arts are growing up, but the majority opinion in the art world is still that tools with undo and tools that can replicate without loss are for unserious artists.
Music is the same way, it's a performance art, and digital sequencing and digital performance have often been considered inferior. Robert Moog, one of the most famous creators of analog & digital synthesizers, even wanted to make his synth a performance instrument, and didn't like the idea of using a sequencer. Sound patches couldn't be saved either, and many famous musicians had enormous careers using Moogs.
It is indeed incredibly unlikely that someone needing a pixel art editor wouldn't want save, I agree with you completely, and I bet @kgwxd does too. But that doesn't invalidate what @kgwxd said. The question "why would you create/edit anything if you can't save it?" was taken literally. @Simpliplant didn't qualify people using pixel art editors, the question said why would you do anything if you couldn't save. As it turns out, people do that all the time. Just not with pixel art editors.
Part of having a productive conversation is using context clues and social norms to help your understanding of what someone means when they say something. Derailing the conversation by taking a comment literally when everyone understands the intent behind the comment is not helpful.
OP might just be in a "release early, release often" stage of development, and the demo might get more impressive as time goes on (color selection would be nice, as well as a preview mode).
But yeah - it is cool - great show for the initial offering.
