I rather liked this game. There were optional ads to speed the game up, and the game play was pretty decent! That was, until the 11/7 update. The developers decided to shove forced ads between every 20 rounds, significantly slowing down game play. They even had the nerve to claim the update was to "provide a better experience." If they want players to invest in the no ads option, this is a pretty scummy way to do it.

A solid game. Not perfect, but one of the better games of its type. Most of my complaints are small QoL changes. The biggest issue I have with it is that most of your progression is active, not idle, and quickly gets to the point of being a major time investment. I'm uninstalling, not because I dislike the game, but because I shouldn't be spending 2-4 hours per day (and it could easily become more than that).

gameplay is alright, however, when watching ads to get double rewards, or for anything for that matter, the ads most of the time force you to go to the play store and when you try to get back to the game all progress in waves is wiped out. spent almost an hour on a run and tried to get more coins through an ad and it didn't even give me the rewards for the completed run, much less twice the coins. waste of my time
