## Description

**Planet Gravity - Newton's Law** is an interactive physics-based game that simulates the gravitational dynamics of asteroids in space. Players progress through levels by completing missions focused on building the solar system step by step.

Using Newton's inverse-square law, the game provides realistic gravity simulation in a sandbox universe environment. It's designed to deepen your interest in the universe while offering an engaging way to pass the time. For players interested in more freedom to create their own universe, additional games "myDream Universe" and "Sandbox Planet" are suggested on the App Store.

## Review summary

Planet Gravity offers a nostalgic and engaging puzzle experience for physics enthusiasts, with enjoyable mechanics simulating gravity and orbits. However, users commonly complain about frequent forced ads, frustrating difficulty spikes after early levels, and some game-breaking glitches. Many mention repetitive gameplay and desire a sandbox or endless mode for more varied play. Level instructions can be unclear or obscured, diminishing the overall experience. Despite flaws, fans appreciate the challenging puzzles and scientific theme.

### Pros

- Engaging and nostalgic for those interested in celestial bodies and gravity.
- Challenging and enjoyable puzzle gameplay for science lovers.
- Fun mechanics involving setting asteroid trajectories and orbital placements.
- Appreciated by users who enjoy problem solving and physics concepts.

### Cons

- Excessive and forced advertisements after almost every level interrupts gameplay.
- Difficulty spikes after level 4-5 make progression frustrating and require repetitive actions or spamming to succeed.
- Presence of glitches causing levels not to register as completed or ads not loading, breaking game flow.
- Lack of a sandbox mode or endless mode reduces replay value and variety.
- Small and sometimes hard to read level objectives, with some unclear descriptions.
