Overall, a pretty nice strategy game. Just a few things.
1- It needs a Fast Forward button: there are times when nothing special is happening and you are waiting to gather some resource and you just want to speed up things.
2- You should be able to rotate buildings: i find a bit annoying how buildings that need Electricity or Water can't be redirectioned. It only makes you waste (scarce) materials drawing some absurd patterns with cable and pipe lines.
3- The prices to order resources should be lower and the hire prices should be higher: should be a little harder to bring people to work in your base, i always do that really quick and without problems. Now, i've been stuck for half an hour or more waiting for things like Components (which are not easy to produce). So, the process of extraction of Science! > purchase of materials could be REALLY slow and boring.
On the bright side, the graphics, music and SFx are good; the gameplay is easy to understand but hard to master (i like challenges); details like the attributes of the workers, the hiden geo-resources, the crazy colonist and other things that complicate up things in a good way.
So, my final rate is: 4 stars. I hope this review helps you to improve the game in the future, i would like to see it better :)
