Pyramidal Crystal

Pyramidal crystals are a type of crystal in Smash Hit. These crystals take the shape of a square-based pyramid, and are the most abundant in the game. They grant you 3 balls.

Pyramidal crystals are first introduced in the first segment of the Introductory stage. Transformational crystals, introduced in Checkpoint 10, will also become pyramidal crystals when approached close enough (after becoming Octahedral Crystals).

Teaser
In Mediocre's blog "First Screenshots of Smash Hit!", images of early checkpoint ideas were posted. These two screenshots had pyramidal crystals.
