Physics Cake

Physics Cake is a 2-D physics simulation game where you draw containers, objects or other shapes, then add physical objects and see how they interact. It is designed as an open-ended sandbox with simple physics, in the style of older online “sand-like” games.

Draw and experiment

You can use lines to draw shapes and containers, and change the simulation’s gravity at any time. Objects can be rearranged after spawning by right-clicking and dragging. The game includes built-in descriptions of its objects and basic functions, available through the ? and ?2 buttons.

Its objects include liquids and gases such as water, oil, steam, ethanol, oxygen, hydrogen and chlorine; materials such as wood, sand, ice, grass, rock, gold and ash; and interactive objects such as fire, jello, marshmallows, pulleys, portals and spinners. Some objects affect or remove others: fire burns, a void pulls objects in and deletes them, and a kill line removes physical objects on contact. Sodium reacts with water, uranium emits radioactive particles, and nanites warp and replicate themselves. The game also has tools that continuously spawn objects, including water, ice, oil, jello, steam, sand, electrons, fire, chlorine, hydrogen and ethanol. Some objects have limits, including one stick figure and one pair of portals, while Sticky and Nanite are each limited to 400 instances. Hidden objects can be found by combining things.

Save and share

You can save your creations and simulations, then share them with others as text files. Saved creations are backed up automatically to Steam Cloud when you exit the game, so you can keep them across devices.
