There's no point continuing this project if the modules can't even be implemented in the real world. So the first step is to figure out whether this is possible.

Will need to consider the following for each module:

• Can it be implemented as in the original game? If so:
  • Will it be practical in terms of cost and effort?
  • What will the installation and setup experience be like?
• If any of the above is a problem, what practical alternatives are there?
  • Will they compromise the original game's mechanics?
  • How will they change the player experience? This covers aesthetics, feel of buttons or other inputs, change in the kinds of actions the player needs to perform, change in the speed of solving the puzzle.
