0rbitalis
0rbitalis is a satellite launch simulator in the style of a retro puzzle. Put your satellite into orbit and compete against the dominant force that shaped the entire universe: Gravity.
Story
These launches are no walk in the park, as there are plenty of stars, planets, comets, pulsars and more to explore. Not to mention competing probes to race against you and even chase yours. Oh, and did we mention the anti-gravity probes?
