the game was always fun, it's just that the lag is annoying and sometimes the game can get buggy, and it's not my device as I have a high end android (and good internet connection), also, there are ads every time I die which is irritating. There's even a glitch where i can watch an ad to respawn with 300 mass and it just sends me to the lobby after the ad. overall it's a nice game, I've played this game since 2017 and it's great, just fix it and stop being money hungry. Add a good update too...

needs to have a CO-OP option and prevent teaming in classic as it makes the game almost impossible for a single player to have a fair battle and chance to get top ten rank. I used to love this game in the last, I found I hasn't had any gameplay issues but like others the ads need to reduce/diversify, it's nonsensical to think someone will want to download a game after been shown it for the 20th time actually makes us less likely to download.

Agario Is a pretty fun game when it's working but when it's not it's the worst. The amount of ads that popped up was ridiculous and the amount of lags spikes I had was even worse. When I would move my joystick to the left it would keep doing to the direction I did last with the joystick until I lost. There are also no people playing battle royale like it doesn't exist anymore. I think that the game should try to fix there bugs instead of creating new events.
