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! 🏰✨

This game was really fun to start, I even stuck through the slow progression. at level 35 you hit the pay gap though. no matter what you do, you cannot progress past this point without digging your wallet out. I've hit the wall in the arena, dungeons and regular gameplay. I'd say there needs to be balancing taking place, but I hit all 3 walls pretty much at the same time. I DON'T THINK ITS A COINCIDENCE. they want you to pay...
