You aren't supposed to get the gel up to the exit.Lord_Ascendant said:I know what to do but I couldn't get the white goo higher than halfway up the third room with the exit and had to noclip and just say it's good enough. 4/5
Full solution:
1) Put the cube on the button.
2) Get the goo into the third room and liberally coat the floor.
3) Get the goo over the floor in the hallway leading up to the third room.
4) Remove the cube.
5) Get goo over the ceiling in the hallway leading to the third room.
6) Place one portal on the floor, one on the ceiling in the hallway.
7) Do an infinite fall and portal into the third room, you should get enough height doing this to reach the exit.
