Man, you gave us the proof that a game doesn't need complicated mechanics or stuff like that. This game is really good and addictive. The controls are yes simple but hard at the same time, adding to the challenge. You, sir, should do more games like this.
If I may suggest something, please add a mute button (for the music and the sounds) or maybe a slider for the volume. That said, great job. Keep up the good work.
