There are only 2 things I want to point out: the zoom animation is very slow, trying to go back from the last level (I presume, couldn't go deeper even though I had enough people) was a bit tiring and I can't figure out how to build a ship, everywhere I try it's red :(
Now, for the good parts - it's very pretty, has a lot of atmosphere and the idea is awesome, I wanted to espace and I need to know if there's more than 20 levels (I think it was at requirement of 100 when it stopped). Great job, please keep going, it's such a unique idea!
