Features & Capabilities

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!

Features:

-- Science!

-- Hundreds of different randomly generated planets and planet features

-- In-depth planet stats screen for the space buffs

-- Rain down comets, meteors, and giant asteroids to give your planet life-- and take it away.

-- In-game screenshot feature lets you capture breathtaking moments to keep or share

-- Slow down time or speed it up to observe your planet's orbit

-- Save planets so you can return to your perfect world at any time

User Reviews

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.

Only 5 stars so ppl will see it. It’s sooooo buggy it lags more than any game I’ve seen. It often switches orientation for no reason. It freezes and crashes

Every time I hop on, it’s the part where it gets so laggy. So I have to uninstall it and download it again, this time, I couldn’t press anything or turn off my phone! what else did you do on mobile?! i’d give it one and a half stars. If it would work, I’ll give it 10 stars.

This is weird where is the original im not trying to be a jerk I'm trying to be nice I like this but there's a catch where is the number 1 and why you get Hygrgen and oxygen 50-50 dose not make a gas giant it makes a green house run away effect but you try your best though (: good luck makeing this better
