## Description

Pet Rock 2 makes planetary science beautiful and accessible.

Start with a simple rock in space; end with a completely unique exoplanet. Choose your star type, adjust the parameters of your planet's orbit and chemical makeup, or bombard it with meteorites and see what happens! Watch your planet grow and change--and if the conditions are right, watch as it develops life. Make gas giants with crushing atmospheres and a dozen moons, a tidally-locked ice planet, densely populated terrestrial worlds, and more. It's all up to you!

## Review summary

The reviews highlight a bold, immersive terraforming experience with realistic visuals and strong educational appeal, plus respect for its potential and depth. However, stability is a major recurring concern—crashes, freezes, and black screens—with particular issues on older devices. Players also want better onboarding (tutorials/sandbox) and note several bugs around atmosphere, water interactions, and gas-giant outcomes that hamper making habitable worlds.

### Pros

- Engaging terraforming gameplay and planetary control with deep, replayable mechanics.
- Realistic-looking planets and a convincing space-science vibe.
- Educational value and discovery-learning appeal for kids and learners.
- Useful save/favorites feature allowing experimentation across many worlds.
- Strong potential and positive reception with ongoing development and updates.

### Cons

- Crashes and severe stability problems (startup crashes, random freezes, black screens) across devices.
- Compatibility with older devices (e.g., iPad 2 / iOS 9) leading to crashes.
- Steep learning curve and lack of clear tutorials; players want more guidance and a sandbox mode.
- Gameplay balance issues where planets become gas giants or uninhabitable due to atmosphere/hydrogen-oxygen mix and water interactions.
- Intermittent bugs related to water/atmosphere interactions that hinder habitable planets.
