Scratch Project 2 (School) --- School Tour

At first, I thought of making a map just like this, but then my teacher suggested making a person moving from rooms to rooms. I tried it, had no idea what to do. The next lesson, my teacher taught us how to do the "room to room" one. I should have finished it but it wouldn't work, weirdly. Then I decided it would be better to make it like a map.
