`Y is flipped downwards, but in your game the top of the view is still considered as being upwards, so I think angles are more consistent this way.`

Speaking of consistency, if you assume that "an angle increments from X to Y" then the consistent solution would be to revert the angle. Another consistency issue: when reverted, the mathematical formulas work without alteration.

But well, i know it's not a big deal, just complaining, that's what i do best.
