This is actually quite a lot of fun. It's hard to learn, fast paced, has multiple game modes and competitive play. They devs keep the special games on a rotation so they don't get boring. If you get really good you can actually compete for money in esports tournaments. It's quite satisfying once you get even a little bit better at moving, flying, and playing the ball/puck/beachball/square ball/football/heatseeker ball (my fav). When players are exceptionally good, it shows, and it's amazing to see just how good some people can get. (ALL HAIL ZEN) This is honestly one of my favourite games of all time, and I've been gaming since NES in the 80s.
I don't know what the person on the other multiple reviews is going on about. A lot of the things they mention are just wrong. But yeah, they do punish players that leave games. Don't be a cry baby and leave just because the other team scored one goal! That happens far too often and players should be punished for it, every time, even me lol. I've had people want to forfeit while 2 goals ahead of the other team! The amount of quitters is absurd and if you do that often you should just delete the game, the rest of the community would be happy. If you don't have 5 minutes to commit to a match, don't start one.
