Love this pixel editor!
I use this editor all the time but encountered a big bug recently. I haven't tested it on normal .png files, but I can't export a .gif file on 0.9.2
I tried to export on 0.9.1 or 0.9 and on these versions exporting worked.
Please fix not being able to export on 0.9.2,
bouncy
also if you need the details of this error, continue this thread.
also again, the editor is great. use it over asprite.
