Overview

About this game

After Earth became unlivable, humanity survives in floating cities powered by the particles of sacred Moon Mice, mysterious creatures once traded by Angels in exchange for worship.

You play as OVO, a synthetic humanoid weapon tasked with escorting Frisk Fawn, a half-angel fugitive, to the Moon to force an audience with an absent God. As Angels attempt to sabotage Moon Mice production, your journey becomes humanity’s last chance to survive.

Gameplay

Engage in fast-paced melee combat with chaining attacks and timing-based encounters. Traverse environments using parkour mechanics, including wall movement and free-flow mobility. Fight a variety of enemies and bosses with distinct behaviors and evolving attack patterns. Utilize a companion system where players influence abilities and combat support. Explore interconnected levels across a sci-fi world set between Earth and the Moon, with ongoing adjustments based on player feedback.
