I play this game and stuck on stage 70, I have no idea do the developer got test the game or not, the game was too hard to clear, I do try send email them but I get the answer is level up the weapon and equipment etc, I try to level up too but I find it u need to take very longtime to up level or the other way it’s paid for it, but the game it’s good to play, I hope can lower down the difficulties on normal mode, u can make ur hard mode to be hard but not on normal mode

Fun but levels are difficult

This game is fun but the levels are very difficult without spending money. Hardly complete level 10 even. I’m very ok with grinding but this requires a lot a lot of grinding to continue. I think some of the updates make the game too difficult without spending money.

Thank you for your feedback! We understand progression can feel tough, but Boom Castle is fully playable without spending. Most players progress by upgrading heroes, wall, and gear, using gem strategies, and focusing on smart choices during battle. We’re tuning balance to make grinding fairer next update.

Update 1.5.0 killed it. Old levels where i used to be able to beat easily now becomes unplayable. Too hard. Burning effect is buggy too. Will come back when new update fixes this.

Developer Response
Thank you for your feedback. The rebalance was necessary to fix overpowering combos and improve fairness long-term. Many players are reaching stage 100, so we believe the game is playable, it's just challenging. But we're reviewing feedbacks and fine tuning. We hope you'll try again and reconsider!
