Thanks for playing!
The mouse control can definitely be a bit unpredictable at times. Personally for me, I found that my mouse movements were the most jittery when I recentered my mouse, so I would always wait until the obstacles' turn to recenter. Probably would have been a good tip to put on the main menu, huh...
There's also an option to adjust the sensitivity in the settings, although I'm not sure how much that helps.
