Hamlet is a redacted version of the famous play of the same name by William Shakespeare and presented as an adventure with a cartoon style. In the kingdom of Denmark Claudius and his assistant Polonius kill the king and queen to seize the throne. It is decided that Polonius' daughter Ophelia should marry Claudius, but then Hamlet, the prince of Denmark, returns from a long journey. Before he has the chance to avenge his parents and free Ophelia, a man from the future on a research mission lands his space ship on Hamlet, accidentally killing him. Since Hamlet is out of the picture, the unknown man decides to become a hero and free Ophelia himself.
Loosely based on the events of the play, the player guides the man through five acts to free Ophelia from the clutches of Claudius. The overall story is more or less maintained, with familiar characters such as Rosencrantz, Guildenstern and Laertes, but Polonius for instance is a green man in a space suit. Using a humorous style the unknown man needs to solve many puzzles in a typical point-and-click adventure style. As it is aimed towards a casual audience, a number of typical elements is not present, such as a conversation system, an inventory, item combinations, or different actions. Each puzzle is set in a single scene where the player needs to click objects in the environment to manipulate them. Puzzles range from simple combinations to much harder challenges that require some trial and error, and sometimes quick reflexes. It is impossible for the main character to die. The main character can be clicked to see his thoughts and sometimes this is a requirement to solve a puzzle. When the solution to a scene has not been found after several minutes, a question mark appears to receive a hint.
