I only recently discovered this game, so here are some feedbacks.
+ Thanks a lot for supporting Linux even in early stage of the development.
+ Ingame all seems clean and bugless (at least noting i've noticed so far), with smooth GUI and all. Well done !
+ I like the general feeling of the game
+ I find it a little tedious to select my factories one by one each time i build a rocket. Would be nice to have an auto-assign option, maybe even included in the techtree as a Logistic branch ? Auto assign, queues, auto move to warehouse... could be techs, then.
+ I'm struggling to keep my bank account positive. So far i've lost my games because of lack of funds after only a few years and 5-10 missions done.
+ Not sure i understand why i can select a launchpad, are they different ?
+ Would be nice to pick my own office, it seems i always start with one in USA.
+ Would be nice to have a visual reminder of the numbers of rockets and missions etc, on the main game screen. Like the little blue circles in other screens, but in the main GUI too.
+ Not much to do beside some very basic stuff so far, but it's a great start for a game done by a not-yet-adult dev within his after-school hours. I believe you can have a great future if you keep delivering quality and content, for this game, but also for any other projects you will work on.
