I really like how it's not enough enough to just hold the bullet over an enemy ship to destroy it, but you have to frantically move the cursor over it again and again. However that also makes the game more about zigzagging with your mouse over your screen as fast as you can and less about the ship that is following the cursor as well. Which is a bit of a downer. I tried to focus entirely on the ship's movement, but than you not only get much less points (as you'll probably destroy less ships as well) but you will also be overwhelmed by a huge amount of bullets fired into your direction, which are near impossible to dodge! I think an ability that boosts your ship forward (like 1/3 of the screen height or so) could really help in escaping such situations though. Put it on a cooldown and it won't be overused.
