Neat :)
I definitely need a right-click colour picker (or shift-click) to work more easily. Can I suggest cutting back your GUI, removing that 3d look, or if you like it too much, then making the pixel art pictures also be 3d like that.
Also your palette is way too saturated. Check out something like http://androidarts.com/palette/16pal.htm for a much nicer set of colours.
Nice, thanks for the suggestions!
I definitely must find some time to make a lot of planned features/fixes. See a list of them at https://github.com/potomak/drawbang/issues.
Er, why can I move right or up but not left or down?
Try it, give me your feedback, and share your pixel art masterpieces!
