If you don't really like that idea, I have a bit more
1. make the map a bit bigger (like a meter on all sides)
2. (workes better if you also do 1) add a small house with a little fireplace this if you put people in, they pop out the chimney
3. add little secrets, like a small room under the map that people would accidentally go in when they fall off the edge if they are lucky.
4. add a dog
