Similar to LittleBigPlanet, the game's main focuses are "play, create, share". They aimed to merge the three aspects into one experience without separating them. Alex Evans and David Smith are the two technical directors;[18][19] Mark Healey and Kareem Ettouney are creative director and art director respectively.[20][21] Dreams uses the BubbleBath engine,[22] a custom engine that renders objects with particles called "Flecks" rather than polygons.
