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.

it's fun except it forces ads all the time and then doesn't give rewards promised for the ads as well as constantly having to reset the app because for some reason it's not working it will load me into the game and then kick me out of the game and get stuck in the never ending loading screen.. I kinda like it.. it's just the most infuriating game I've ever played haha oh and it would be cool to see a team battle mode and it would also be cool if there was a solo mode

It's fun, 2 complaints, though. The ads are annoying but I understand that they're necessary, but sometimes I watch an ad for something and I'm not given the reward. I'm not sure if it's a connection error, but it is frustrating. Another thing, it gets very laggy when a lot of players keep duplicating. I wish there was an option to play on a lower quality so it wouldn't lag as much. +1, some ads start playing right after I join a match??
