Wasted around $40( until 2 June 2025) but with very little return, developers made some stages too difficult, some too easy. Some units are horribly difficult to kill (eg orc bird elite)and some extremely easy, difficulty imbalanced.Their customer support is horrible, sent email about the issues but no response. Stage 52 is bugged( tried it 50+ times but cannot pass it) but developers are doing nothing to fix it. I am thinking of uninstalling this game if I cannot pass this level by June 30.

Thank you for your feedback. We're sorry you feel that way. We have many players progressing to high stages and we are tuning the balance according to feedback. Stage 52 can be tough but it's not bugged. However we understand it can be challenging. We are a small team and we are doing what we can to improve the game. We hope you'll try again!

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!

edit: been playing for a while now, could feed the entire world's population for years with the food I've wasted grinding through the lvl 20's to 27, where I'm presently stuck. still hate the energy system, but I log in with 300+ food to waste on grinding lvl 27 like an insane madman, so whatever. need to fix the card drawing during gameplay. instead of rolling 2 useless traps, please lump them into a card that say trap or something and gives you 3 trap cards to choose from if you want a trap.
