The Butterfly Sign: Human Error

The Butterfly Sign: Human Error is the second chapter of the first person detective video game in which we are playing as a sole survivor of a serious terrorist attack. Protagonist is the only witness of the incident and his fate depends on his memories. Thats why he goes in for a desperate measure: he takes the experimental medication called Rammex, which immerses him in the depths of his mind and makes him accurately recollect a chain of events, which had happened. While wandering through his own memories, the protagonist has to look for evidences and learn bits and pieces to find the guilty persons

The main feature of the second chapter of the game is the concept of multilevel memories. Drug effect of Rammex makes the protagonist remember everything he has ever known, while maintaining freedom of action and choice inside his memories. This means that if the protagonist finds the device with Rammex in his memories, then theoretically he may use it

The second distinctive feature of this episode is the spatial confusion inside the memories or, put simply, looped space. Some of the memories will cause errors in memory, thus creating looped space: while trying to leave the location by all means, the protagonist will make it into it again and again and so on ad infinitum. You will have to put your thinking cap on in order to solve this puzzle, to break the loop and to get out.
