I have decided that my final prop mechanic will be split into three different puzzles (gates). My first gate will be one that shows the player that the prop (heart book-bag) is what is causing the door to react. The second door is a puzzle which using the symbols on the bag/heart to solve the 3 step puzzle lock. The symbols must align in order to unlock the door. The third door is the music door, or the Simon says door. The player must listen to the tune that the bag/heart plays, and then they must repeat the pattern on the door.
