What's New

Version 4.9.36

This update includes a lot of bug fixes, including a fix for the Time Traveler bug and a significant increase in the size of the UI for those who were complaining that it was hard to read. We’ll be adding custom size controls in a future update, but in the meantime this should allow players to get back into the game more easily. As always, thanks to the players who helped us diagnose and fix these issues, and happy terraforming!

This game is something I was looking for. It’s great. It has stunning graphic of your planet changes as you terraform it. It’s so satisfying when you see that water on Mars, and then clouds slowly forming on its atmosphere. All this to finally see green spots of bushes and trees slowly showing up. So great, balanced and fun to play. Every planet comes with a different challenge and different difficulty of terraforming. The game doesn’t have annoying ads! And has great system of ads rewards if you wish to watch them. It is just perfect. I hope devs will keep going like this. It’s the best game I ever played on my phone. All the other games had the annoying ads that just show how greedy the developers are. I know everyone wants to earn something on these games but some of them are just ridiculously filled up with ads. I dump them all with the first ad popping up. When I see devs not being greedy, I feel I really want to support them. Good job!

Good game all around

Dio Kitsune

First off I will preface this by saying I’m only working on my first planet for now but I will say from my experience the game is very good especially considering purchases are entirely optional and the game itself is free

However, somethings could definitely be improved on such as the graphics of the water when trying to build a new colony/ outpost, specifically it saying they cannot be built under-water where no water is shown, including when attempting to place a new mine at an outpost.

Another issue I encountered is that the tutorial isn’t particularly helpful and I instead found myself relying almost entirely on trial and error, for example currently I hate heat rising by +1 per minute and it says to reduce the rising heat levels and there was no focus on being able to pause the progress for any reason you should wish such as not wanting to drown your colonies and outposts while you sleep/ are at work.

Fascinating and well-paced


A fascinating, compelling and well-made strategy game that’s very satisfying when you balance all the necessary parameters and succeed in terraforming your first planet. My initial attempt for Mars did well until I neglected to factor in how quickly melting icecaps raise water levels. All my original colonists were drowned, so I tweaked the settings and re-established colonies until things were back in balance. I’m now working in Venus, a completely different challenge. I love the factual elements, and this sim game is worth it for the experience so far. The pace is great, I can set things up, make a few rough calculations at critical points, and check in periodically to tweak the settings, manage mines (essential for income) and monitor the O2, H2O, pressure, temperature etc. until things start to come together. Seeing the planet change from barren to habitable feels like a real achievement!
