Baby Time is a pixelated quest platformer that features cooperative play. While taking a walk with her family, a pregnant woman named Fifi suddenly goes into labor. The family heads to the hospital. The player must direct the characters through the various floors of the building.
Fifi can't jump, but the player can direct her to drop to lower levels and move objects. For example, they can direct her to use planks to build footbridges across gaps and pick up letters to open exit doors.
The player can switch to other characters at any time in a co-op manner. Each member of the family possesses unique qualities. For example, Fifi's husband, Yann, can jump and use computers to open non-exit doors. Their daughter, Juju, can't operate switches or turn on lights. She's afraid of the dark. That said, Juju is the only character short and confident enough to move through narrow passages in the walls to reach hard-to-reach levers. She can also jump like her father.
Baby Time isn't an overly complicated game. The player merely needs to direct the characters in cooperative ways to help Fifi reach the exit door on each level of the hospital.
