The ad sponsors that you are using for this app, are locking my phone while playing the app. It forces open the Google Play store which is a violation against the Google Play policies. I have pinned the app so it cannot force open any other apps (Google Play Store) during, at which it freezes my app. Please reach out to your ad company to fix this issue. I believe you've done well and not forcing ads during gameplay, however this discovery is unwelcome and won't be tolerated.

The game is fine, but the progression is just too slow. It takes longer and longer each level and seems utterly pointless attempting the same level over and over for pitiful rewards. I'm assuming they want you to spend in order to progress. sorry but will uninstall.

Thank you for your feedback. We’re sorry it feels that way. The game is designed to be playable without spending — over 90% of players progress by upgrading heroes, wall, gear, and using gem strategies. We're reviewing early difficulty spikes to make progression feel smoother. We hope you'll give it another try!

way too hard, even with spending a lot of money! I was stuck on a level, spent $20 for VIP benefits and some coins to upgrade my weapons and after a month playing, spending time and money I'm still stuck on the same level. kinda got boring. my expectations are if someone spends $20, can at least play the game with some strategic challenges not impossible to pass. I think it is a very fun game if you are willing to spend $100 monthly but I can't afford it.

Thank you for your feedback! We understand how frustrating it is to remain stuck after investing both time and money. Purchases can speed up progression, but they don’t guarantee passing a stage—the main stages are designed as strategic challenges. We’re reviewing difficulty and progression, and hope you’ll try the next update! 🏰
