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!

It starts off great. But once you get to the higher levels, it is clearly designed to not give you the cards you need to progress. During each round, after a certain amount of kills, you get three random cards to pick from. These are either characters or power ups. You can use dice to refresh the options. I have rolled these dice, or watched adverts, to refresh the options but they are always cards you don't want. It knows the ones you need and use, so it makes sure you don't have these.

Thank you for your feedback. The random hero/card roll is part of the gameplay and it should test your strategy skills. It's based on luck, so we understand it can be frustrating. We’re working on improving the game mechanics and we plan to add new gaming modes in the next update. We hope you'll try it! 😊

i would like to rate it higher. Because after many hours playing. i believe this to be one of the finest TD type games out there! BUT theres issues here i think need addressing. Mainly balance and the reliance of nothing but LUCK with power ups between waves. Aside from that, the developers are doing a great job with expanding the game through updates and constantly improving the game. So well done 👍
