Amnesia Custom Story Puzzle Ideas

[FlawlessHappiness]

Depending on the story and the environment you could build something like a ritual…having a lot of entitys and every one needs to be in a specific area…the cliche would be a star on the floor and the player needs to put at every tip a candle and then light them in the correct order…
[if sucessfully there could be a setentityactive which activates the leveldoor in the middle of the ritual…and a billboard which constantly grows or something like that.]
But the star is only an example, the task could also be to tidy a shelf and order the books in alphabetical kind or by the size…even depending on your story.
Some flashbacks about how it was once could help the player to know what he is supposed to do, maybe the player had an uncle who had the compulsion to sort books by size…or sort boxes by their content…or a table where you need to put several bodyparts you can find on and sort them like you would build a frankenstein^^ Would be great if, if sucessfull, a monster spawns on the table and smashes the door for you

Spawning a monster if the player fails, would not be the greatest solution.
Maybe rather have 2 ways completing this. Either finishing the ritual, or failing it.
If you fail the story will change completely.
