This game got me lining up my cursor with the stars for my shots. Really cool design and polish. The timer is a really nice touch and the UI looks great. Did you use the real gravity equation for the calculations? I think it would be really nice to have the planet resetting size tied to a button rather than every reset so it would be easier lining up shots, but that might clutter up the controls. By the way, I LOVED the scroll mechanics. I am literally the number one enjoyer of having the scroll wheel as a main part of the game. Its underused and probably because of controller support.
