To get the high score achievements, it's essential to amass a whole flock (16 birds) as early in each game as possible (for clear skies) and keep the golden geese bonus running. Without the massive bonus points from it, getting to 1 mil points in a single run is impossible. If you pass the second ocean without much bonus time, restart.
Upgrades are too expensive for the little damage they add. Not being able to dodge is annoying, especially since the auto-targeting is random and does not aim at the most dangerous enemies. Fun game with potential, but 3/5 max at this stage.
I love the Decision series and was delighted to see this game. The upgrade system with different kind of people required seemed cool at first, but seen as these folks are (a) limited and quasi-finite ressources as well as (b) almost completely random in appearance, this runs dry very quickly. The result is that you are left with tons of money (from engineers in your team, not in those petty factories) to upgrade your buildings, but without any of the specialists required. Please fix that or allow retraining of professions, especially of the useless citizens.
Can't seem to finish the game, as the upwards jetpack does not work. Everytime I jump and press up + c, I always rocket in the direction I am looking. Shame, really.
