Okay this is a suggestion for late game stuff.

Ik this game is not focused on colony building, but i think this would add some extra depth to the game. Maybe there could be a new mode called colony building where you can research a landing pad so colonist rockets can land? Maybe they have needs and in return they can work in farms and mines to gether resources? The game art style is absolutly adorable but it would be very cool if you can add some function to the structures you build in-game.

Only a thought, people, only a thought.

I was thinking along that lines as well - having to build other buildings based on the mission and time limit.  Landing pad, colony base or warehouse and a rocket that lands and picks up refined ore or uranium - meet that quota!  And any landing pad will of course need an antenna to guide the rocket in - hope you have it built before it arrives or it might crash.
