- Heart Cubes have no official name.
- There are only three collectible Heart Cubes in FEZ, one in the Observatory, another in the Metatron Room, and another one in the Monolith Room.
- There is a non-collectible Heart Cube (known by fans as the Love Cube) in the Temple of Love that only appears in when the previously mentioned three Heart Cubes have been collected. Entering a certain code will make it disapear, and restart the game. (see Temple of Love for more detail)
- The design of all four of the Heart Cubes is widely believed to be a reference to the Kokoromi logo.
- Heart Cubes do not appear in your inventory.
