Devs need to address bugs!

It’s a good game and I definitely enjoy it, but like most of the posts on here I am frustrated by the lack of attention and fixes to the problems in the game - one of which is really hurting the developer’s pockets. Not once have I been able to click on the timed special offer and get through to spend money on the game (iPhone Plus 7s), each time the screen will go dark and a little loading screen knight starts running with 3 dots under him... and it stays that way forever until reboot (I actually can still click through him and click on the special offer again...). You should really fix that, maybe with some of that extra money you could afford to spend time fixing the glitching, the tiny and misplaced hit boxes (likely due to my device size being scaled up), crashes and loading screen hangs, etc...

You guys have a decent product here, show it some love.


About time!

At first I really didn’t think I’d like this game too much ,I really only downloaded it to try it. I was so sick of those pay to play games I was willing to give anything a chance. Thank God I was wrong, this game instantly pulled me in and I haven’t been able to get out since. It plays like the old mobile games, you get good, develop some strategy, you get well rewarded. I have so missed that in mobile gaming these days, most of the newer games are really designed to empty your pockets and not offer much reward. That’s what’s special about Frontier Defense, and if you happen to spend a buck or two it really feels worth it, not like somehow you got cheated. I sure hope you guys don’t mess this formula up in an update. Otherwise, great job!


Needs a restart option

I’m absolutely in love with the game but I’m constantly hitting walls that take me days or weeks of constant grinding to get over. There should be a restart option where you go back to battle 1 but now you earn more money. You get to keep the stars on your heroes but they’re level 1. Also 5 stars isn’t enough, you should get 5 white stars then when you reach level 250 you can become 1 star but this time it’s like green or blue or some other color to show that they’re getting stronger. You guys need to pay more attention to the game.
