The best pixel tool ever, and its free: GrafX 2

GrafX 2 is the one of the best pixel programs ever.Having used the Deluxe Paint line of pixel software on Amiga for a straight 10 years, from Deluxe Paint 2 (my first commercial purchase) to

Dpaint V, this feels like coming home from a looooong trip :D

Working with 8-16-32 colours is really challenging and motivating.And it makes filesizes really small :D and artwork really sharp.Ideal for mobile platforms.

I have to admit I like it more than ProMotion, which nonetheless is a great tool, too.But sometimes, the simpler the better.
