Sequel to Pet Rock, Pet Rock 2 – Planet Simulator expands on the features of the first title adding in-depth planet statistics, moon generation, asteroids, rings, and above all more planets. Additionally, the game’s HUD has been redesigned and a screenshot feature added.
The app lets players design a planet starting from a simple rock in space. As variables like distance to the parent star, orbital speed, and element makeup; the planet changes accordingly. The app employs actual exoplanet science to change the planet to everything from hot rocky worlds to gassy ice giants. The goal of the game is to create the conditions suitable for life that we know of, i.e. moderate temperature, atmosphere, water, and carbon.
