It seems Godot Engine is good for more than making games, as the FOSS pixel art tool Pixelorama will show you. Only a few days ago, this impressive application had a big new update bringing in a new UI, options for each tool, a colour picker tool, rulers and guides, a mini-canvas preview area, a preferences window and a Greek localization.

It really is coming along nicely, hopefully by us sharing this more artists out there might find a tool they love to use. Since it's cross-platform too, thanks to the power of Godot Engine you can use it on your platform of choice.
You can see a video of it in action below with their feature highlights in 0.5:
