I'd read over the Strings library section in PiL. Should answer all of your questions.

I love picross (or nonograms as they are originally called). Looks good.

I find it a bit funky that you're including art from games that "inspired" Netherworld in your press release. Someone who just gives a cursory glance might assume that the people behind those games have some investment in this. Do you have their permission to use the artwork in advertiseme...

That's perfectly fine if you are dealing with small rectangles, but you'd probably want to ...
