About Heart Box

Professor Rat's experimental puzzle rooms are the only thing standing between a little robot and freedom. Work through 20 types of physical objects — test cubes, bowling balls, spring trampolines, dynamite, conveyor belts, fans, lasers, portals, dynamic saws, and more — to guide the robot out of the charger. Every room is a physics sandbox where the solution depends on using the right objects in the right way. Clear the puzzles to unlock funny cartoon cutscenes, or jump into the level editor and build your own rooms.

Heart Box is a free Cottagecore game you can play instantly in your browser — no downloads or installs required. Tagged brain, cartoon, casual, educational.
