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! 🏰

It started well, but lately the game has gotten too stingy and less appealing despite their silly contests. Just recently they downgraded the rewards for the daily quests, plus they decreased the gold as well so you spend more. The packs they sell are pitiful and not worth it, don't spend your $$$ on them. You're better off spending it on coffee or something that brings contentment. This game sucks now....

Thank you for your feedback! We’re sorry the game feels less rewarding now. The rebalance was necessary for long-term gameplay, but the game is still playable without spending. We’re reviewing daily rewards, gold income and pack value, and working on more ways to get resources. We hope you’ll try the next update! 🏰✨

It was a decent game until the latest update. Gold and diamond rewards were cut 40-60%, while base upgrade costs were significantly increased. This makes it almost impossible to play beyond a certain point without paying real money. The developer is making the same changes to their sister studio's game, Last Legion.

Thank you for your feedback! We’re sorry the latest update feels this way. The rebalance was necessary for long-term progress, as some rewards were too strong and broke balance. We understand concerns about rewards and upgrade costs, and we’re adding more ways to progress. We hope you’ll try the next update! 🏰✨
