I remember there being a voice interaction with someone talking about how Astra uses her powers at the cost of planets (correct me if I'm wrong). How exactly do you think that would work? And what is her general lore?

It is one of the most common mistakes that will making getting one taps and head shots in general harder. Instead, panic STAND! Getting into the habit of holding A and D when you see an enemy and have the advantage to take the first shot...
