Evaluation
Particulars launched out of Early Access on November 19, 2014, as a complete product featuring over 100 levels across ten chapters, full voice acting, and the Particlepedia. The developer news leading up to launch shows a steady stream of pre-release updates adding chapters and polishing gameplay, culminating in the November 19 release post celebrating the game's completion after years of development. All developer communication after that launch post is absent — the last news entry is the launch announcement itself. There are no DLC listings, no roadmap posts, no announcements of future content, and the store description does not reference any planned additions. The game was released as a self-contained, finished product and no post-launch content was ever announced or shipped.

About this game
Particulars is a game with a unique combination of arcade-action and puzzle gameplay, set in the mysterious world of subatomic particles.
Taking control of a single quark, you must negotiate the fundamental forces of the universe. Other particles will push and pull at you - you'll always be on the brink of losing control and being dragged towards annihilation!
Woven through the game is the story of Alison, a young physicist struggling to outrun her troubled past. Her journey through the subatomic world is drenched in memories (both good and bad), and will ultimately lead her to some powerful revelations.
