Just picked this game back up after a couple years and I've only noticed one issue, but it really makes the game reek trying to deal with it:

The controller deadzone is absolutely gargantuan, so big it has to be a bug, no way by design. My stick's at almost 50% lock before I get any output, which makes anything high precision next to impossible.

This is the world's easiest bug to fix though, just add a deadzone slider.

I know this is a bug because the deadzone on iOS is perfect.
