The Firefly Diary is heavily based around the Vita's touch capabilities. As Gematsu reports, you control a pair of firefly-like fairies with the task of guiding a young girl through perilous ruins. One of the fairies is based in a light world, the other a shadow world, and you switch between the two to solve the game's puzzles. Here's where the touch gameplay come in: The light fairy is controlled by the front touchscreen, while the rear touch pad moves the shadow fairy around (Push Square notes you can tie both fairies to the touchscreen if you prefer.)
