Thank you for the feedback!
I thought it was cooler if they expanded slightly. Initially it was meant to indicate outwards traveling bullets just like the jump, but I realized it was kind of hard to tell the difference. I sort of just kept it because it felt cool, and also it won't look weird when launching right out of the player. The scale might be too much though and it may be expanding too slow. You should still be able to aim where the mouse cursor is, one of the projectiles will still go to it. The main mechanic with that was you had to time the focus properly to get it to hit.
