Just a general video game addiction thing, I suppose but still somewhat notable:
I frequently groan, grunt, complain, moan, or make other sounds of pain or displeasure upon being hit/dying in video games now. I don't know if it's because of Touhou or just playing too much in general, but I've started doing that for the past two or three months now.
Particular irritating events that are prone to making me outright shout with irritation:
Losing a life on any stage that isn't 4 or better (usually followed by a restart)
Losing a life from not paying attention
Losing a life in general
Losing in general
Being on the receiving end of a critical hit, or being hit by an especially strong attack/one that kills me/one that I should have been able to dodge but didn't because RNG (other video games)
Missing an attack, especially one that had a high chance to hit/was an attack I was really counting on (other video games)
I've also started cheering myself whenever I do well in video games, too. Usually when:
Evading/Dodging an attack
Defeating a boss (Including stage 1-3 bosses)
Taking down an enemy/accomplishing an objective/winning a round in a FPS
Winning an extend
Winning in general
