Spike Collider for longy.

SpriteChange.cs

public class SpriteChange : Monobehaviour
{
	public Sprite[] spriteArray;
	public Sprite spikeSprite;
	public SpriteRenderer spriteRenderer;
	public int currentSprite;
	
	private void OnCollisionEnter2D (Collision2D col)
	{
		if (col.gameObject.tag == "spike")
		{
			spriteRenderer.sprite = spikeSprite;
		}
		else
		{
			spriteRenderer.sprite = spriteArray[currentSprite];
			currentSprite++;
			
			if (currentSprite >= spriteArray.Length) 
			{
				currentSprite = 0;
			}
		}
	}
}

so now for some reason the spike destroys the heart all together and still when i collide with the floor the sprite changes
