Overall it's a great game. Just on the game alone, I would rate 5 stars. I have it at 4 though since there are red blips everywhere that you can't remove after clicking on them, each one is for you to see the multiple microtransactions all across the screen instead of maybe just 1 red blip on the shop icon. Other issue which is minor, the name taken feature, so many people play games and take the good names then quit so those are forever gone.

I spent 40 minutes on a ranked game. I almost beat it, I was on the final wave. I died and that was fine. I clicked to watch an ad to double my rewards. While I was on the ad my finger accidentally touched the ad, sending me to Google Play. I immediately tabbed back to the game but it had reset completely so not only did I lose all the rewards, I lost the ranking benefits of that masterfully played 40 minutes. Pretty disappointing.

This pay-to-win game is fun but frustrating. Progress often feels blocked unless you spend money. I've been stuck at level 190 for weeks due to a lack of items to increase my power. I bought the no-ads upgrade for about $6, which helped—without it, the game would feel unplayable. While enjoyable, it can get very expensive if you want to advance. The biggest disappointment is that it doesn’t work offline, which was my main reason for downloading it to use on flights. Purchased two months ago.
