### 5/5 — Most buggy game ever

*2026-05-17, version 6.3.1*

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

### 1/5 — I was expecting it to be a good game :(

*2026-05-16, version 6.3.1*

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.

### 3/5 — Bruh

*2026-02-15, version 6.3.1*

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

### 4/5 — This game is awesome and has so much potential. It’s amazing

*2026-01-26, version 6.3.1*

This game is absolutely amazing, and has so much potential. But I beg you, please update it, add some more features, more toggles possibly, more possibilities! More stats. This game is absolutely amazing, and love it. Please keep working on it if it’s possible. ❤️have a great day.

### 1/5 — L

*2025-12-19, version 6.3.1*

As soon as i opened the game, my phon froze completly, it took 2 minutes just for my phone to turn off

### 1/5 — I would have put 0 stars if I could

*2024-05-25, version 6.3.1*

I got stuck in the game nothing was working at all I could even turn my phone off and it kept on glitching it’s just horrible

### 1/5 — Too many problems.

*2023-12-03, version 6.3.1*

When I opened the game, the only thing it did was crash the game I literally had to delete the game because of that cause of crashing my whole phone. I had trouble trying to turn on or off on my phone it was terrible! My phone almost died away. And when I got enough hydrogen and oxygen it would just turn into a gas giant. I trotted burning all the hydrogen and oxygen out it still was a gas giant I need you to get the game OFF THE APP STORE.

### 1/5 — Make it better!

*2023-11-30*

When I opened the game, the only thing it did was crash the game I literally had to delete the game because of that cause of crashing my whole phone. I had trouble trying to turn on or off on my phone it was terrible! My phone almost died away.

### 4/5 — Gas giant

*2023-11-14, version 6.3.1*

Every time I make a planet and try to make it habitable it gets gassy ;( how could you developer

### 1/5 — This game is terrible. It’s impossible to make a habitable planet

*2023-10-18, version 6.3.1*

When I’m playing the game and I add more water, it increases the atmosphere thickness too so when I’m done adding water, it says the atmosphere is too thick when I go to the events tab and lower the thickness of the atmosphere. It removes water too which makes it impossible for me to make a habitable planet
