Ads in a $4.99 game?

To be candid, I actually like the core gameplay mechanics. Its hard porting a game like RE4 to a touchscreen device, but they did a decent enough job and its fun as a result. However, with the last few updates theyve added advertisements into the game and for something that cost $4.99 I dont think that is acceptable. If the game were much cheaper or free then I wouldnt have a problem. However, I bought the game at full price and would prefer to have my game ad free. I suppose you could call this a protest review.
