Cogito: Requiem

Cogito: Requiem is a 2D action game where you dash freely through a harmony of music and sound effects.

The setting: a world where humanity has migrated into the digital realm and vanished, leaving behind only the SI—artificial intelligences who once had humans as their masters. As Cogito, you race through this world where their remnants linger, set on "ending" the SI that have fallen into error.
