People will occasionally turn invisible. Now I am NOT talking about the upgrade classes that CAN turn invisible, I mean, literally any tank will randomly just blink off my screen, making it near impossible to kill them, since I CAN’T SEE THEM WHILE THEY’RE SHOOTING AT ME. Would be appreciated if you could update the game so we can use all the upgrade classes from desktop. Other than that, just terrible controls. In addition, my iPhone is now bent from rage from these issues that make the game near-unplayable. The ads are obnoxious, and some will not let you exit the ad. I’ve had to close diepio , and when I reopen it, I immediately have about 15 safari windows open, all ads. It’s absurd, and I think at this point, I’m just deleting it. It’s more of an ad than a game. You will get no more ad revenue from me, as I am uninstalling. I will also be using Adblock when visiting ANY of your sites, since you seem to not care about good game development. Congrats on turning a dedicated gamer away.
