this looks soo gooood!!!!!

I managed to build main (or rather development) on arch linux without problems (https://github.com/LibreSprite/Dotto/tree/development). Must appreciate how easy it is to build compared to Aseprite. Tho its still quite far from usable even tho it has 1000 commits, but they are putting lots of work into it.

they are "open source", but under their own license (eula), it used to be fully, there is a libre fork and they are working on a rewrite https://github.com/LibreSprite/LibreSprite

Aseprite is technically open source.. https://github.com/aseprite/aseprite

Are you using an orthographic view?

I saw sth very similar a while ago in a cover of Enter Sandman by Motorhead (animated video)

(random fact, their lead singer and bassist went by Lemmy)
