It is common for parents to boast about their children's grades in order to make them feel better. (Which I'm not sure if the kid is really happy or otherwise?).
When he wins some archives in the game, my son is overjoyed. In order to keep up with the arrows that are falling as fast as a downpour, you must use the keyboard keys. He pressed it 100% correct!
This isn't going to happen on its own. The only way to win the game is if you are willing to put in the effort and understand the mechanics. (It's annoying that the keystrokes are so audible.)
Distinguish what constitutes your child's genuine happiness, as you indicated. Or is it truly what you do for your own gratification?
The name of the game is "Osu".
