This is an amazing game. Beautiful music, simple gameplay mechanics and well, we are all fascinated by space. Thanks for deriving me of my sleep tonight. I'm playing through the tutorial now and if I may suggest one thing to add to the game is the choice to sort the list by letters and proximity so we can choose the closest asteroid to mine or which type of asteroid. You really should think about making this into a full-on game so we can all enjoy it's full glory and beauty. An idea which I hope is in swirling around in your mind.
