Crayon Physics Deluxe

Crayon Physics Deluxe is a puzzle video game designed by Petri Purho, known for its intricate two-dimensional physics simulations and emphasis on gravity, mass, kinetic energy and momentum. The game includes a robust level editor and allows players to share and download custom content through an online service. The main objective of each level is to maneuver a ball from a specific starting point so that it connects with all of the stars placed on the level. The player achieves this by drawing physical objects on the screen to influence the ball's movement, such as creating rigid surfaces, pivot points, wheels or ropes that interact with the ball in various ways. The player can also nudge the ball left or right and use rockets present in some levels as part of the solution.
