[Edit] A release date of October 17th has been announced.
Some of you might be familiar with Picross. It's a puzzle game most notably released on Nintendo handheld devices where the solution to the puzzle creates a picture (and the puzzle itself is creating that picture). Using logic for how many blocks are together in a row and where the gaps should go, things can get pretty hectic. It's kind of like Sudoku meets Pathpix (although I am sure that developer took his inspiration from Picross in the first place).
Edward Brown, an ex-Popcap developer is bringing Picross to the iPhone with his upcoming game Paint it Back. You use the same process to repaint lost works of art in an art gallery. The game is bright and cheery, and the pictures all come with amusing names. Have a look at the trailer and see for yourselves.
The game is due out sometime in mid-October, and being a fan of Picross myself, I shall be looking forward to playing it!
