I find some secret medals
1)Playing the blues: dont edit the drunked guy sign
2)Fear for fetus: click in the pink demon behind the tree in the level of hell
3)Fetch dog fetch: in the same level, grab a stick an then, use it in the dog
4)The human pinata: use a stick on the hanging soul in the same level
5)The mask we wear: In the level of the street, after killing the guy of the sign, grab one of his bones, then go to the puppy's room and give it to it, and then open the chest and combine the balls inside it with the mask of the wall.
Yeah, I know I forget some medals. Anyway good game. Good luck
