How to Improve your Aim and Reactions on Keyboard-Mouse
This game is Called OSU and it is very helpful with reactions and mouse control this can also improve your aim significantly, It helps alot with your mouse movements I recommend playing this game and any game on low sens as you will be more precise with everything you do such as flicks and tracking, if you are a high sens player playing osu in low sens should get you in the grove to use low sens in any game. This is just a recommendation of course if you are high sens and think your a beast in high sens then stay there but if you are high sens player and feel you could be alot better or you feel your aim is not the best then maybe just try low sens. I played high sens when i first got my pc but quickly transitioned to low sens as detailed above and now i am 10x the player i was then.
