The idea of matching the color of your block to the same color in a line of colored blocks to clear them is simple concept that was executed poorly. The game will continue on, eventually making me bored with such basic gameplay that has no variation. This goes on continuously, with not much of a way to lose. To add on, you'll be in the middle of the game, and suddenly, and ad pops up. Ads make the view of the game impossible. It doesn't even pause the game, so as the ad takes over your view of the 300 lines you've cleared, it keeps going. I had to scramble myself to keep the game going before eventually double tapping the home button and closing it altogether.
This game is in need of fixing, especially ad wise. I get you need money, but if you're going to obstruct our view, at least pause it so we can continue to attempt to enjoy this game. Making variation to lines would help me be more interested. Maybe add a mechanism where you can get a power up that clears lines, no matter your color for a short time.
Otherwise, gameplay gets boring real quick.
