Great concept, and great execution. The game is fun to play and I like the unique way you increase the difficulty by cracking the screen to hide the buttons and even adding in minigames to play. There's even a backstory and narrative to follow along. This is a great example of a simple idea expanded upon and executed well. One thing, pressing 0 to start the next level stopped working for me around 3 levels in, luckily after the dialogue where he tells you that you can use your keyboard. I could only go to the next level by pressing 0 twice on the physical keyboard.
