Fable -- if someone is stuck in a game and asks for help, I don't think that person would be upset if one of the few people who has actually played the game agrees to help them.
Though some people enjoy spending weeks and weeks playing a game and hours and hours solving a particular puzzle, there are other people who want help after awhile.
As you can see by how busy our Hints forum is, this is true of almost all adventure games, not just Limbo of the Lost. Hundreds of people visit the Gameboomers Hints forum because they are stuck, even (sometimes) desperate for a solution.
That's one of the things we do here, try to help people.
