Flash game perfection.
I can honestly say that this is one of the greatest games I've ever played... period. It's highly addictive and makes me feel like I'm not wasting my time by playing. The soundtrack is nice to listen to for the first handful of puzzles. Then it starts to get old. So I noticed the handy mute option. Now I use my own music as a sound track.
I've checked out other picross/nonogram games, including Picross DS, and this has the best interface out of all of them. But I know it won't last forever. Please bring a sequel with even more.
