Beautiful concept - the tension of the peaceful exploration of space/extraction of its resources and the timer ticking down for the sun exploding is a really great idea. Once I got the controls down, many things made sense. My brain immediately thought if the robot went into the sun, it would explode; I realize why you didn't do that (a little too harsh with the controls + position of the planets I assume) - but part of me did wish for that reality.
Astonishing game; this was a really cool experience.
