For level 11 you need to finish parkour then find a white pillar going up to get a key then unlock stuff to the next key then escape. For level 12 just find 3 paintings then escape. For level 13 find 5 stars then the monster will appear behind you so you need to look at him for a bit but move while looking you can hear him teleport behind you so be quick. The first plush is on the right side of the map the second one is on the left side but in the red room the third one is straight ahead right infront of the exit. ;)
