Prototyping the Navigation
As with any game, it is always a good idea to lock down the basic functionality by using simple proxy objects wherever possible. This helps keep your development time agile, allowing you to adjust your game plan when an idea doesn’t pan out. Even with a team of programmers, you can easily hit technical restrictions that will force you to make changes. Game play itself may require extra thought; what looks good on paper doesn’t necessarily equate to fun game play. Creating mock-ups with simply geometry allows you to test your ideas without the overhead or commitment of expensive (in time and/or money) art assets.
