Hello! This is not meant to be nitpicky! But just in case it confuses someone.
In the resources section for Triggers To Restart Level, specifically Unity Docs - OnCollisionEnter2D()
It takes you to https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnTriggerEnter2D.html
Shouldn’t it take you to the following? https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnCollisionEnter2D.html
Should problems such as this be reported elsewhere? My apologies if so!
