The thread has a few grammar errors, and I hope they won't appear in the hack (example, "video's" instead of "videos," capitalizing every word in a sentence, and "i" instead of "I," and a few other things..). Also, the cave entrance here looks weird,
it should, in my opinion use another tile on top of the "door."
