Do you have fun when you're playing this game?
If yes, then keep playing
If no, then don't play anymore
Seriously, why are you asking a forum if you should play this game? We (at least myself, for that matter) don't really care whether you continue playing or not since it doesn't affect us (me).
P.S. there's nothing wrong with feeling like there's no point in playing this game because that's exactly what it is: a game. If you're not getting paid to play a video game then it's always going to be a waste of your time, so either you waste your time clicking circles or you waste it playing/doing something else.
