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.

Thank you for your feedback. We’re glad you find the game fun and entertaining. We understand that the energy system can be frustrating. We’re working on balancing the game and improving resource availability. Your suggestions about the tavern and tower upgrades are valuable, and we’ll consider them for future updates. We appreciate your support!

It's fun for a little bit but gets very grindy with no option to purchase no ads. The randomization is not a good couple with gems that can make a specific build. Unlocking more is a double edged sword because you get specific heroes you want to use but are less likely to get, so you find yourself losing after the first upgrade because you didn't get what you needed.
