Building the Universe is a time travel and building game that starts at the Big Bang, the beginning of the universe as we understand it. The player arrives in the Cosmic Egg, a ship capable of traveling through time anywhere in the universe, and even altering its scale to shrink below the size of an atom or larger than the stars

The objective is to build the universe starting from the first fundamental particles and ending with a Solar System and habitable Planet Earth. From a first-person perspective, players will need to capture sub-atomic particles floating through space and combine them to make the first elements in the universe in this indie, puzzle-solving adventure. Tools include an extendable claw, and electromagnetic tool, and a particle launcher, all of which, when used in the right order on the right particle, can create new particles in the universe.
