The goal for each stage is to find and obtain a treasure chest located within and the difficulty varies between puzzles, but even the earliest areas had some players perplexed. We don't view this is a drawback, but a plus -- genuine gameplay hurdles are a rare commodity in today's industry and we're pleased to see a game that doesn't make any excuses for being hard. It is also mean. If you mess up at any point during a puzzle, Zack will die and you will have to restart the challenge from scratch. Some of the challenges lasted between 10 and 20 minutes depending on the player. Amazingly -- and this truly takes a lot of nerve -- a company representative said one particular puzzle in the game can take as long as two hours to complete. How would you like to die at the end of that one and have to restart the entire process? The game ranks you on time and whether or not you asked for a hint and compiles and end score based on both. Theoretically, there's a lot of replay value to be had for gamers who want the best score.
