Player advancement is represented with player levels. Each time player solves a puzzle, defeats opponent, finished quest etc. (s)he receives experience. After certain amount of experience is gained, player levels up. This is (almost) standard for RPG games. Players do not gain skill points through usage of specific skills but rather through redistribution of skill points that are gained after player levels up.
