In an alternate 1950s universe, there is a small spaceship diner, where the position of the orbit determines its interior environment. Explore three distinct gameplay challenges that metaphorically represent the real euthymic, manic, and depressive mood episodes of bipolar disorder.
Doppel Diner
SteamAtompunk cooking simulator with a twist.

Manage a small 1950s-reminiscent diner that orbits the planet in open space. Based on the planet's rotations, the inside environment changes, creating three different playing conditions. Learn to manage the resources carefully and lead the diner to success!

Doppel Diner is not just a story about a diner influenced by external weather conditions. It is also a metaphor for managing the emotional states of bipolar disorder: a mental illness that causes dramatic mood shifts. The game's goal is not to explain what bipolar disorder is, but to offer an experience of how it might feel like to spark important conversations and shift the stigma around mental health.
