I don’t know why other game don’t have it. I just followed brackeys tutorial. I planned to have a hill blocking you from being able to jump out of the map but still good idea
It's one of those little things that is easy to forget with a short deadline. Plus I don't think a lot of people think to look up how to implement it. (I actually haven't learned how to do it myself - but most of my games in the past few years have been browser based so they didn't need it).
