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.

I don't know what happened in the last few days! 10 (TEN) ads before your first round each time you open. then an additional five after first round, two of them video you must watch! that's it! sorry, but that's completely unreasonable. the app is done, deleted, and will be forgotten. I know ads are necessary, but not 15 per round. that's insane.
