I love the concept of the game. It’s not something you have to sit and think about or strategize over if that is the type of game you are looking for. I understand the need for ads as well, as this is how game developers make money. However, this game has them way too frequently. You have to watch ads for every upgraded gun, key set, and I was seeing ads pop up nearly every other piece you clean.. and since it only takes a matter of seconds to “clean” any one piece, seeing so many ads gets old real fast. I will most likely delete the game for the amount of ads. Otherwise, the game is fairly amusing.. but I could see this getting repetitive really quick if you get bored easily.
