The chart illustrates the first draft of everything participants will see during a playthrough.

Shown is visualization of what core gameplay would be like. This method allowed for rapid iteration during this phase of development.

The graphic shows an early draft of the field layout, that was tested in the pen & paper prototype.

I asked colleagues to help me test my designs and assumptions on paper.

Most modifications to the game layout and its rules happened in this stage. No big changes in design were necessarcy, once I started executing my ideas in the engine.

Before starting implementation, I created a diagram of all important aspects I needed to keep track of during development. This allowed for easy planning and effective time management.
