Heart Box

Heart Box comes with a small backstory. Professor Rat loves physics puzzles and robots, so he built one of his own: Robby. Unfortunately he gave Robby a weak battery, and the little robot has to keep recharging and take part in the professor’s rather crazy experiments.

Those experiments are the levels. Each one is a puzzle room, and getting Robby through it means interacting with the physical objects inside. The game frames them as physics puzzles, so the solution lies in how you use the objects in each room. The long-term aim is to get through all of Professor Rat’s rooms and finally free Robby from the charger he depends on.

There is also a second way to play. If solving rooms is not what you are in the mood for, the Level Editor lets you create your own puzzles. That turns Heart Box into a small toolkit as well as a game: you can rebuild a room idea you liked, or invent a contraption entirely of your own.

1. Look around the room and find the objects you can interact with.
2. Use those objects to open a way forward for Robby.
3. Guide the robot until he is through the room.
4. Clear every room to free Robby from the charger, or open the Level Editor to build your own.

Try each object once before committing to a plan. In a physics room, seeing how one piece behaves often reveals the whole solution.
