Con Dated look and feel
It looks like it was never supposed to be used in the modern world.
Con Lack of modern features
Some modern features that are necessary to do pixel art creation for game dev work are lacking.
Con Unintuitive interface
Zooming is reversed, the screen flickers a lot, and the flip/rotate selection is very buggy (selection will re-size though it should not). Essentially, the interface of Pixel.Tools is clunky and unintuitive.
