there's no point in playing this game because I'm no longer advancing. I work my way up the leaderboard, this last round I got first place but it keeps telling me no rewards to collect because I didn't play last week. And you still haven't fixed issues that were an issue 5-6 years ago. It still gets really laggy, my circle doesn't always go in the direction I tell it to, watching ads for rewards don't always give you a reward and i watch bigger circles eat a virus without it splitting them up.

horrible. I can tell that I'm playing with tons of bots, but that's not even the problem. I don't mind that, I don't care as long as it's fun to play. but the fun is snuffed out, when after every game, there's an ad. imagine you die immediately after a minute, you just watched an ad... congrats, watch another one! oh and what about the being online gifts? yeah no, watch an ad to get it. the game changed a lot and only on a bad way.

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.
