The idea behind level 4 was that this was a different section of the lab from the previous level. Level 3 was the building of the robots and level 4 is the repair lab section hence the use of the chemicals and the mechanical robots seen in the left window. When designing and creating this level, the idea came that the whole lab was connected and then at the end, we will see an overall view of the full building so that the player knew they had progressed and escaped the lab. This design is missing a few elements which will be seen in the game, such as the doors and the floating elevator platforms which the player will have to use to navigate around the level and escape the lab – the reason yet again for not including these in this design is because Ryan needs them separate to incorporate them into the game so that they move.
