This was a great spin on a clicker game, really spiced it up by adding the asteroid defense aspect. The camera shake and zoom animations really made the game feel dynamic, great choice to add those!
It was kind of hard to keep track of the drills on the planet when so much was happening at once, especially once got smaller. I'd have liked different level drills to be different colors, so I could have a idea of which ones I want to protect more.
