This is one of my favorite apps, possibly one of the best apps on the market. The gameplay, the options, the usability, and the fact that you can unlock just about every feature without spending real money. Except sometimes I’m impatient. So I did spend real money. And even though I spent $10, I still get ads after every other mission, sometimes every five missions if I’m lucky. It’s extremely irritating that I’m still getting ads, but also so many ads, after spending so much money. That seems like it deserves some attention. Another mildly annoying aspect is that you can’t turn off the sound, making it impossible to plug in some headphones, listen to music, and play the game all at the same time. The gameplay sounds are always on. That’s an option worth looking into. If I’m in the car and I’m in charge of the aux, I can’t just sit in the back and play this game while I ride around. I can’t do anything AND play this game because it’s super loud and there’s nothing I can do about it. One more thing worth mentioning is onscreen graphics. Before, when you’d walk under the dripping water or when the giant zombie spat green stuff at you, you’d see the effects, either falling water or a green smudge on your screen. One of the more recent updates has done away with that and it was a cool, random little feature, made the game more realistic. But truthfully, just the ad situation and a mute button is all I’m really concerned with, if someone could maybe look into fixing that. Thanks.
