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.

Great game! I just hope we don't have to use diamonds to sweep stages. I have 300+ energy atm and I don't want to use dias just to sweep stages. Also, buff mages. Archers seem to be OP in my experience so far. Especially the short-ranged one.. I forgot the name, Aldo or something. anyway, keep up the good work!

The difficulty level is tuned too high. I got stuck at STAGE FIVE, and even after dumping all the free gold into gear and hero upgrades, something I didn't want to because there will surely be better stuff later on, I'm still stuck. Feels like a waste of time. Game runs smoothly and graphics are decent. They have a demon 'hero' planned for the future, so I'm going to uninstall.

Thanks for your feedback. We're sorry stage 5 felt too hard. We did a difficulty rebalance in the latest update and we're still fine-tuning it. Focus on upgrading wall, heroes, using gem sets, and checking enemy resistances. As for the heroes, we have many fantasy races and we don't discriminate any of them. We hope you'll give it another try! 😊
