A brief talking-head video where Ben Tristem introduces how to use PlayerPrefs in Unity.

Ben recaps where we are, and continues building the PlayerPrefsManager.

• Add temporary “Core Game” panel.
• Translate & scale the level canvas.
• Adjust & prefab the camera.

• How animators, states & motion clips relate
• Adding multiple animation states & clips.
