Follow the beat. Tap to move forward. Paint over all the walls! - nmskr.dr
You appear as a white arrow within a black map and grey brick floor. This arrow turns to the beat of the background music. To move, tap the screen. The objective is to move whenever the arrow faces the path correctly. Running into the wall will lose a life; the amount available being displayed in the top right corner. However, the game can be quite lenient in that regard. Successful completion entails colouring the whole map. While running into a wall loses a life, you are free to run over fragments of the map that have already been coloured in. The game progresses by means of having more complicated maps, and by having the arrow turn faster on account of faster music.
