About Nira: Across Skies
A true 3D Momentum Platformer about flow, freedom of movement, and human community in a solarpunk world.
The core gameplay is about true momentum without limits.
The game environment shows a world where humanity is rebuilding.
And the story shows an interpersonal conflict between two sisters as this world is threatened.
Or I guess you can ignore the last two and just blast through the game, that's fine too.
Story
You play as the titular Nira, who's job to help a city with their power issues forces her to cross paths with her sister in an attempt to save the world from an otherworldly force threatening to destroy society.
Gameplay
Run and jump both on the ground and on walls to parkour through the towns and cities of Solarvale. There are no speed limits and the core of going fast involves discovering and executing on ways to gain, redirect, and keep your speed. Momentum is at the core of all mechanics and systems, so don't lose it.
