Please fix. After closing the game during mid battle. Going back into the app and to continue the match where I was playing. All the gears are on the bottom and nothing is working and would lose the fight automatically. Somehow it's glitch or something. Sometimes can move them but they are stuck on the screen and doesn't work. All you hear is the ticking sound

ads keep crashing the instance. can't win when you can't get bonuses due to difficulty scaling. reducing as with difficulty scaling videos are necessary to advance and its way more common. I get to the last round and it crashes and restarts the game. hope you're making money on my views. because I am not getting anything from them.

It would be the best game if you weren't cheated out of your reward for watching ads. From the beginning it wouldn't let me view the ads and gain rewards. now I'm lucky if I get through the ads and get rewarded. And now it seems I get halfway through the ad only to be denied the ones I need to continue further. And as gears that are denied are left on the playing field. This game has lots of bugs to work out. That's if the developers really care to fix these issues where most won't.
