The campaign features a series of missions at each planet in our solar system. Each planet comes with a unique way of controlling your asteroid, which is used to collect other asteroids and proceed to the next level. You can also create and share custom puzzles from within the game. The game has Newtonian physics where gravity, mass, and velocity all interact realistically. Puzzles can consist of some clever designs and multiple solutions are usually possible. While Luna’s Wandering Stars is a challenging game, fans of physics-based puzzles should find a pleasing experience.
