It's pretty fun. All games waste your time. If you're getting angry over losing, stop playing. In my opinion, you're only mad because you're bad, which inherently isn't a bad thing, but you're also salty about it. Git gud or stop taking it so seriously (and yes the music is good you're right)
side note, uh... although fun, a lot of the other games are more entertaining imo. so you're partially right. it sucks ass relative to most of the other games
