Fun game, prepare to spend $

This game was very fun at first. Free app, different challenges, smooth control, and easy interface. Once you play the game and begin to advance, the difficulty of your opponents increases so much that you are forced to spend money on upgrades for weapons, defense and other tech items to even get through a mission. Also more ads pop up that are 30 second long videos without the option to skip.
They definitely lure you in with the free app but be prepared to spend a fair amount of money if you want to progress / avoid annoying useless ads.
When will marketing teams realize that they are spending wasted money to get an ad in front of people that are annoyed and will boycott the very product/service they are trying to promote by forcing the ad on their "potential customers"..?!?!
