I actually cheated a little bit with that trajectory thing. It's simulated, not calculated. I just running my calculations 1000 ticks ahead of real time and record points where the astronaut ends up and then literally "connect the dots" :)
Haha, but you did it. The result is what counts.
Check out our Demo during Steam Summer Festival: we rebuilding that game from scratch and releasing it on Steam this autumn!
