Picross e7 perfects the formula

With each Picross e game, Jupiter refines the formula. Picross e2 brought us Micross, Picross e3 brought in Mega Picross and Picross e4 introduced 20×15 puzzles. Sometimes, it can feel like all the biggest and best things have already been done. Yet, with Picross e7, we see important alterations have been made to an already solid formula.
