I got a new wired mouse because my wireless one would act all weird and I got sick of it dying on me. While I got used to it for playing LoL, I still haven't managed to adjust in OSU . It sucks because I just recently got better at "fast" songs where I gotta press a lot ever since I learned to use 2 fingers for the z and x key. I used to be good at hitting notes far away from each other, but now I suck because I'm not used to the new mouse.
