Imagine having a personal portal to the solar system right in your pocket, allowing you not just to look at the stars but to interact with the physical laws of distant worlds. This experience is made for anyone who has ever wondered what it would feel like to step onto the surface of another planet and wants to try it here and now without putting on a spacesuit. Each new planet you choose becomes a small experimental space where a simple jump reveals the important role of gravity.

You control a bouncing sphere, but the main feature is that its behavior depends directly on the selected planet. On one level gravity allows long, floating jumps, while on another the pull downward becomes relentless, requiring a completely different approach to control. This turns the gameplay into an intuitive study of astrophysics: you are not reading about gravity — you are feeling it with your fingertips as you try to score the highest number of points in a constantly changing environment.

One of the central features is the interactive gravity laboratory, where numbers turn into an engaging experiment with your own mass. With a light motion you can set parameters and instantly see how your weight changes under conditions different from those on Earth. This is not just a calculator but a visual demonstration of how the physics of Mercury or Uranus affects things familiar to us. You literally see the difference as familiar kilograms turn into lightness or, on the contrary, into noticeable heaviness, offering a fresh perspective on our place in the universe.

All your achievements in mastering gravity unlock access to interesting facts. By collecting stars and moving forward you gradually reveal unique cards with information about the planets. Progress bars fill up as you advance, turning the process of learning into an engaging search for planetary data. Instead of a boring encyclopedia, you get an interactive reference that unfolds step by step, making the topic of gravity clearer and more accessible.
