Not happy with the update

I’ve played this game for years off an on and I’ve always loved it. I still do. A while back I had to get rid of it to free up some space and just recently came back to it. I have to say, I’m very disappointed that they’ve added a “forced tutorial”, ie, one that can’t be exited early or avoided altogether. I do appreciate them adding a bit of guidance for new players, but there needs to be an option to skip the tutorial. I have played the game before and don’t need a guide dragging me around and forcing me to do things. It doesn’t help that you can’t cancel actions except by exiting the game and fully closing out of it. With no way to be precise—especially when choosing where to put your cities—it’s really obnoxious to have to close and reopen the game to reselect where you want your first city. That’s to say nothing of not being able to pick where to put your first mine.

The game is great, but it still needs a few tweaks, such as being able to skip the tutorial, and maybe arrows that you can tap to be more precise in location selection (these already exist in the mining interface). Some planets have very little “safe” area to build on—so they aren’t destroyed as the water level rises—so precision is pretty important.
Otherwise, it really is an excellent game that I have had and will continue to have loads of fun playing.

Blown away

I don’t even know where to begin with this app.
It’s 100% as cool as it sounds. I saw it on Facebook and I never download them but it showed how well it was rated in the App Store so I knew it had to be something legit. Gave it a try and now I’m addicted to it. There isn’t really too much I would change to the game other than being able to see ground level and have more control over what happens to the population. As far as what the game is, terraforming a planet, they did an amazing job. I’m sure you can control more but on the basic difficulty level (I highly recommend to start with) you can control the temperature, oxygen, pressure, plant life, money, population size. Everything is highly sensitive. Finding a balance takes time. This is a game that won’t take up too much time at once. You might only play this game a couple times out the day but it’s necessary to check in on your planet every once in a while. Random events and scenarios happen to the population and the planet which I really love.
From a meteoroid on track to hit you, to the population finding a great athlete to honor amongst them. It gives the game a story. You have to make a decision when those things happen immersing you into the game even more. And of course Every action has a reaction. The main task of this game is finding that balance. I’m so glad I found this game. The space nerd in me is ecstatic! I highly recommend!!!

Love this game but a few glitches

I really was enjoying this game a lot. I finished a few planets and then it was time to do earth. When I started earth it was already inhabited and everything was where it was supposed to be with oxygen, etc. I thought this strange. So I started doing research and mining. Went to bed. Got up next morning and my mines were lost to rising seas and all the inhabitants were gone. So I checked all the stats and everything was still perfect with oxygen,water, etc. Weird. So I built the thing that causes minus 4 water and built more mines. Next day it said they were lost to rising waters but that was impossible since the water had actually gone down a couple of hundred. So aggravating. So now I’ve been waiting for the population to build back up. My next culture point is at 4 billion so I’ll be waiting a while. Lol Was really enjoying this game until this happened. You have to be able to do math and figure out actions and counter actions. Taxes the brain. But when the game just erases things built and people for no apparent reason it’s frustrating. If you judge this game on the first few planets I played it is an amazing game. I was actually going to buy one of their packages but decided to wait after this earth catastrophe. If it goes back to normal I will probably wind up purchasing a package. It’s that good a game when it plays right

Thank you for your review, and sorry to hear you've experienced this -- how frustrating!

The Earth level is one of the hardest levels in the game, second only to Ragnarok. It is suffering from global warming; to combat this, build ice launchers from the very beginning and try to build the Soletta as soon as you can.

Let us know if this helps!
