I would be giving this 5 stars, but the game is broken and no way to contact devs. The boss feature doesn't work. It only allows you to watch an ad but no reward and no boss fight. You cannot sweep the level even with an ad, again no reward when watched. Tried that 3 or 4 times with each boss since I wasnt sure if I had missed something. Didnt even get tickets. I will update my review when a fix has been applied.

It had so much promise at first but then it became the plain as day money grab that all of these apps end up being. And if you don't pay you have to watch a crazy amount of ads just to try and have a chance at beating some of these levels. And one of the worst things is that in one of their events they force you to pay for one level in order to keep getting more free rewards, so like I said total money grab game here don't waste your time.

I was going to give you 5 stars. great game, nice time waster, plenty of ads to watch to help along the way, even not that expensive to buy upgrades. however there's intrusive ad type things that randomly pop up telling me there's a virus in my phone and occasionally restarting my phone in the process of closing that out, tells me there's malware installed in the code somewhere. you might wanna fix that.
