Please keep in mind this was like 6 years ago (as of writing) so my memory isn't the greatest here.
This will be a generic "shit at aiming on FPS game so surely osu! will help me improve my aim and not cause me to only play rhythm games and never touch FPS games again" so nothing insane here.
Now, if my memory serves me right I was playing a Fortnite Roblox clone on a laptop me and my brother would share. I was really struggling to aim and I wanted to improve my aim so I searched on YouTube how to do so. I ended up finding two videos from a Fortnite creator and one from Kariyu back when he was making those sort of videos. So on 17th, May 2019 I started playing and have been hooked since. I remember spending the first few months of my playtime in Serbia and Bosnia when visiting family.
I ended up picking up full alting after watching Verto's video about it before I was even in the top 1,000,000 and its been my preferred tapping style since.
