The builder is the object that you control to build games inside the audio environment. With this builder you can move around, place and edit building blocks.
For controlling the builder use the directional controls.
The directional option works more like the controls of a simple puzzle game. This makes the builder move in the direction of the arrow that is pressed by the user. So if the keyUP is pressed the builder moves upwards and if keyLEFT is pressed the builder moves left.
