Artwork and screenshots had previously been provided for htoL #NiQ: Hotaru no Nikki, but not until now have Nippon Ichi Software published a trailer for the game.

Hotaru no Nikki is an upcoming platformer that’s releasing on the PlayStation Vita, in which you must guide a mysterious, young girl through the use of a light and a dark firefly, after she inexplicably awakens in a dungeon.

The game is set for a release via both PlayStation Network and retail stores, on May 19th in Japan.
