Yes, you got that right, ship is out of control so Hero destroys minimal and dies by saving everyone - Gets most point (Hero ending)
And if you don't put restrain, that means you are going rogue with the hijacked ship - Gets lower point (Rogue ending)
However there was a third ending I planned was for 0 point, (Evil ending) , it wasn't meant to go infinitely down, but because of lack of time I couldn't implement it :P
Also thanks for feedback, I'll increase the speed in future versions. :)
