I was able to learn well until the end because you explained it in a calm and orderly manner. I am not a complete beginner, so it was okay, but I think it would have been good if you had defined the concepts once to help me understand variables, triggers, and responses. I had a hard time applying them because I just memorized them without fully understanding their roles. Except for that part, it was more useful and helpful than any other ProtoPie lecture I have seen! (This is my third ProtoPie lecture)
