So you're telling me you could be SSing a map with 10 seconds to completion but you'll exit the game (not just the beatmap but the osu client) and then restart and do the same map again?
If you're closing the game no matter what, perhaps you're not having much fun playing. Try and forget about score or combo or accuracy and just focus on having fun and enjoying the music.
Press Shift+Tab and you can't see accuracy or score either. Try it. It might help. If not, try to find maps you like and you might not leave those maps. I hope this helped you.
