Just hope it can keep up the development to contend with ProPixel Studio then. Even the budget ProPixel2D gives it a run for it's money (minus animation). :)
As a beta tester of ProMotion I can say that it`s still very much in development. If ProPixel2D had animation then I`d look in to it more seriously as it looks like a great program but as it stands I, and most other pixel artists I know need at least basic animation for our work.
Oh and I still do not think that there are any pixel art programs on the PC that come close to the almighty DPaint on the Amiga even though many have tried to copy it.
