Hi. I really enjoyed it.
I got the same problems mentioned here with ports and pylons. Couldn't make them work unless reloaded, also, some things like water pump cleaning on the edges etc didn't worked until reload. Overall great experience.
I would like it to have a small story - you as a player are playing as AI sent to various planets to terraform them before humans will arrive. The first building should be special one - landing place of the rocket. And the various islands should be changed to different planets.
