The three stories are unrelated, but share the same situation: all three protagonists you play face constraints in their life, and are struggling to overcome them. The game is very well written, and like Photopia, uses colors quite effectively. One thing I like about the game is that it is thought-provoking not only about real-life constraints, but also about a 'meta' level constraints that we, as IF players, face when playing a game. Although it is quite good at anticipating your next moves and giving the appropriate responses, Constraints does not let you deviate from the pre-determined storyline. For example, there is no way to change or extinguish each protagonist's desires (which would have led to some interesting results, because constraints arguably can only be considered such as long as we desire something). As such, the game itself is a good example of the central theme.

If you enjoy well-written story-driven IF titles, Constraints is well worth your time. It is very well-written, thought-provoking, and quite original as far as the premise goes. Highly recommended.
