Frustrated

Previously really loved this game but I didn’t have saved progress, started over. Spent money. As soon as I spent the $10, my game started crashing like crazy. Can’t make it through a wave. I have current version, restarted phone, plenty of memory and perfect performance for my iPhone 17 pro on every other app. Only this game has decided to freeze my phone and make it impossible to play. Wasted money

fun until they lie

i spent 2 hours trying to beat a so-called "easy" level. used all my gems (over 900) watched all the ads for the upgrades, and still couldn't do it. they force you to spend money once you get to a certain point if you want to progress. ridiculous

In a league of its own !!

I just want to say ever since I came across this game I just simply fell in love with its own gameplay and concept. I really like how everything in this game works and is balanced out perfectly. Every single level is just awesome !! Great job on the game Team you guys rock keep making more good ones 💪🏾❤️💯💯💯


PS. I do want to mention that it needs to be a lot more challenging, as in making the levels harder I would definitely encourage it I would make me enjoy the game much more thank you 🙏🏼
