- The game concept involves a woman who discovers her reflection is a sentient being trapped in a shadow world within the mirror. The two players work together across dimensions to progress through levels, fight enemies, and collect items to find an oracle that can free the reflection.
- There will be boss fights between levels to mark progression. Environmental interactions and dialogue between levels will add substance and help players connect with the characters.
- The final battle involves fighting the oracle over five levels. If defeated, it is freed and the reflection emerges from the mirror in a closing cutscene.
