Amnesia for me?

[Romulator]

BTW is there some sort of pointer? Like something that shows you the direction to go? Something that prevents constant backtracking?

There is backtracking in Amnesia - however somewhat minimal.

Without trying to spoil too much, the game has three main levels called hubs. These levels branch off to make more levels for the player to explore, each hub containing one major puzzle. To solve that puzzle, you need to explore the various environments, not necessarily in a particular order in some cases, but it is in all means solvable.

There are some cases where backtracking is prohibited however.
