Projects That Impress Recruiters

Game Polish Techniques

Polish is the difference between a prototype and a professional game. These details create the "feel" that makes games satisfying.

The Polish Pyramid:

                  / │ \ (SFX, music, ambience)

}

IEnumerator ReturnToNormal()
{
    float t = 0;
    while (t < 0.1f)
    {
        transform.localScale = Vector3.Lerp(
            new Vector3(1.2f, 0.8f, 1f),
            Vector3.one,
            t / 0.1f
        );
