Limbo's Gaol is a simple walking game where you need to solve some puzzles and uncover the story behind the world you are put into. This is more of a prototype game, made to gather info on how each player perceives a story depending on which protagonist they play as.

I recommend playing the downloadable version of the game, as it offer a better overall experience. It has better visuals, load times and smoother gameplay experience. The web version simply offers easier distribution for all platforms.
