It's unclear why this image has an absolute path but no others do. They should probably all be relative, as the other three are.

Especially if this is for a tutorial, you need to add docstrings to all of your functions.

This:

self.img.setpos(enemy.img.pos()[0], enemy.img.pos()[1])


can use argument expansion, i.e.:

self.img.setpos(*enemy.img.pos())


That pattern can be used elsewhere you're indexing into the position.

This:

enemy.health += - self.power


should be

enemy.health -= self.power
