Click to begin WAD or arrows to move Mouse to Aim Q to fire blue portal E to fire orange portal F to fire green portal (green tiles only) S to interact with objects Go through the portals to reach the exit. You must have both the orange and blue portals open at the same time to go through them, but the green portal can be used on it's own. BTW you can take ANYTHING through a blue or orange portal Start Thinking With Portals!
I'll add more levels using the green portal later
