Reviews
Description
Welcome to the whimsical lab of Professor Rat, a clever inventor who created Robby, an adorable little robot with a small quirk: his battery drains quickly, so he needs constant access to charging stations to stay powered up. In Heart Box: Physics Puzzle Game, your main mission is to help Robby navigate hundreds of wacky, carefully designed experiments spread across the lab, using real physics rules, logic, and creative thinking to get past every obstacle in his path. This family-friendly puzzle experience is made to delight players of all skill levels, from casual players looking for a quick mental workout to dedicated puzzle fans seeking a tricky new challenge.
Each level tasks you with getting Robby safely to his charging station before his battery dies. You will interact with a wide range of lab objects that all follow realistic physics rules: push blocks, activate ramps, adjust moving platforms, and rearrange environment items to create a clear path for Robby. You can take as long as you want to plan your moves in classic mode, or test your speed in timed challenge modes if you want extra difficulty. If you get stuck, you can step back, re-examine the level layout, and try a new approach to find the perfect solution that gets Robby charged up in time.
