Portal - My Levels - 4

Level 4 - The first proper puzzle room. This one involves using the Pellet to open the door. There is also a small box with two switches in it; one to move the ramp to push the Sentry into the toxic waste and the other to activate the crusher (appeared in the Portal trailer, never made it to the game), choose wisely. Another feature I made, which is a recurring theme here, is the generator (The generator is shown in greater detail in another submission).
