Power management is a cool concept for that theme. I find the simulation to be too difficult for getting started though. It took me several retries to just figure out why I couldn't see the asteroids even though the radar had the power flow on. I think it would have been nice to start with a regularly functioning ship and managing power and radar before losing one of the power cores.
And a star map with the flight path would be nice as well instead of a simple progressbar.
But still, great idea and cool visualization.
