Hey sorry to bother you again, I've just updated the game with a sensitivity slider and the default sensitivity is now lower, if the default is still too high for you, you can access the slider after the tutorial by pressing ESC
That seems to solve it! I slid it down to .1 and that feels about right for me!
I did find a bug while playing, if you're at any interactable station when hitting escape you can get the mouse locked but have the station up, kinda soft locking you.
Avoiding that though, I did wind up getting to day 2 and was just short of the quota! Neat game, pretty interesting mechanics, I liked the ramp up in difficulty for sure.
