Interesting mechanic! I really liked the visuals.

It was just a little bit tedious to wait for an asteroid to be facing the right direction, if there was a way to speed up its rotation while I hover over them I think it would be a little more fun. The hitboxes are also just a bit too small, when I have to wait for the thing to do a full rotation because I misclicked it's frustrating. But the mechanic was definitely enjoyable enough for me to play to the end, well done!

The concept is cool, but think it would be better if i could charge the amount of speed i want to input into a asteroid, sometimes it takes too long get close to the blackhole and then i miss hit a whitehole and have to start all over again, other than that its all fine, cool visuals too btw.
