Description of the Issue:

Projectile doesn't reach the exact spot the mouse is aiming when outside of deadzones.

• I am using Google Chrome

• I am using YOUR_BROWSER

When outside of deadzones, aim directly to your left, the projectile will be slightly off from it's mark.

Additional comments or information:

I have a feeling I know what this issue is, but adding this just in case it proves to be more difficult than I thought.

This has something to do with using clientY.
It only seems to be an issue when out of the Top deadzone.

If the game is first loaded while on a 1920x1080 monitor, everything works.
However, if the game is first loaded while on a 1600x900 monitor, the calculation is off, until you move it to the bigger monitor then back.

I think this may be solved by having proper scaling. If not, I'll look into the whole clientX/Y thing.
