Heart Box - physics puzzles game

Heart Box puts you in charge of rescuing a small robot trapped inside a series of experimental chambers designed by the peculiar Professor Rat. The goal sounds simple enough — get the robot out safely — but the physics-driven puzzles standing between you and that exit are anything but straightforward.

Scattered across each room are objects with real physical properties: bowling balls that roll and knock things over, spring trampolines that send the robot airborne, conveyor belts, pneumatic tubes, movable platforms, and more. Lasers and dynamite add a layer of genuine danger. Figuring out how these elements interact is where the real thinking happens, and solutions rarely come on the first attempt.

Twenty different interactive items appear throughout the game, and combining them in unexpected ways is often what cracks a particularly stubborn puzzle. The difficulty builds gradually, giving new mechanics time to sink in before layering on more complexity. It's the kind of game that rewards patience and a willingness to experiment rather than rushing toward an obvious answer.
