A sealed jar that runs its own oxygen cycle.

Pour in sand and water, seed algae and daphnia, add a fish. Then leave it alone. Plants make oxygen by day, everything breathes it at night, and the jar either finds a balance or it does not.

This is the full game, running right here. On your phone the jar keeps living in your pocket, with more save slots and The Planted Jar pack.
