Are you playing on a laptop by chance? I included a sensitivity slider but I've noticed that laptops tend to give much stronger mouse inputs, not sure why.
Ok cool. If it's anything like my laptop, the lowest sensitivity setting may still not be enough. I may have to add some kind of "laptop mode" that lowers the sensitivity by a much larger amount. Also the 208 seconds is a bit of a "strategy" one of my viewers discovered ;)
