We get a clearer picture of the story and gameplay in Hotaru no Nikki (Firefly’s Diary).
Set far in the future, htoL#NiQ follows Mion; a little girl that wakes up on December 31, 9999 not knowing where she is or how she got there. Your job is to help her escape this place by controlling one of two fireflies that guide her, and by using objects to augment your play and maneuverability.
The two fireflies exist such that one lives in the light and one lives in the shadow, each one having different abilities tuned to their environments. The light-loving firefly can make plants grow to open new paths for Mion, while the shadow-loving firefly can move through the shadows and use a “shadow link” skill to move objects.
While exploring the ruins you can find memory fragments in hard to reach places. These memory fragments give you a glimpse of someone’s past; these replays giving you an idea of what happened in the past and the truth about how the owner became a corpse.
There’s also a bunch more screens, check them out below;
…and some artwork of Mion;
htoL#NiQ comes out June 19th in Japan.
