Awesome and unique idea to be in control of such a decimating, inanimate object! Also a bit challenging to decide if the asteroid is bigger or smaller than you as you are zooming up on it! I had to actually give up and just avoid hitting rocks cause I wanted to see the end xD which I also appreciated the stats of how big the asteroid got and its nuclear decimation equivalent haha! Some playtesting notes from me are some of the rocks move at the same speed/direction as the player so you never catch up with them, and the dither on some objects doesn't seem to make all of them solidify. With those two factors it ramps up the difficulty of hitting smaller rocks than you, not sure if intended as much.
