For this level in Portal 2, I wanted to focus on the teaching the player in the level. My level focused primarily on the use of the game’s tractor beams and how they work in conjunction with the emancipation fields. The level starts out with a very simple introduction to the mechanic. No input other than walking is required from the player but it teaches them the fundamental idea that the tractor beam can push things around. From there the level introduces moving the beam with portals and the expands into another section teaching about moving cubes and yourself with the beam. The final room of the chamber is meant to have the player demonstrate that they have learned from the previous sections, combining all the different skills that they learned. Given the small scale of the level, I have found from testing that it is very effective at communicating the mechanics and still challenging the player.
