This App is Very fun and Challenging. I was planning when to tap the screen, But then I noticed there is actually a White bar that raises up and ends the level when You take to long. Unfortunately, This made me a little mad, But a little confused at most. Since the game Puts you on the same level you lose at, And not at the beginning again, I just shrugged it off. I think you should add a little free shield thing, Like if you watch a video a few times a day, You will get a free shield each time you watch one. I think it's a little silly to have to pay to get shields, But I understand when this game is free. At least make the videos limited, I mean come on. Besides that, I LOVE the game! ❤️
