Bullets seem to occasionally miss the mousepointer.

[Sidaroth]

Two likely causes:

• Phaser's pointermove event (or our storage of it) is not updating as expected.
• The radians we return from direction.angle() is wrong. (Though it's seemingly correct elsewhere...)

[Sidaroth]

Direction vector is likely wrong due to the "offset" we add to avoid shooting from the center position of the sprite.
