Luna: The Shadow Dust (2020)

Switching between a boy and his small companion turns each tower room into a conversation about what the two could do together. There is no written or spoken dialogue to follow, and the contained rooms help focus attention on the current puzzle. An adult should expect to help coordinate actions and interpret some less obvious visual rules. Shadowy imagery and an emotional story of attachment and separation make it a thoughtful choice rather than an entirely carefree cartoon.
