I loved the concept, it just had some flaws.
What I'd love to see in the full version is a diplomancy system, so you can ally with the aliens, I tried to do this by placing humans there so they could become friends or something, but that didnt work.
Another thing I'd love to see is a tutorial. So I know what to do. I could only create an atmosphere on 1 planet and then boom, I couldnt do it anymore, which became boring in the long run.
the graphics, please dont change it. It looks so pretty
Overall good job, waiting for full release!
