Interesting concept, but A. you need to teach the player how to use the paint cannon (specifically the key binds used to control it)) and B. why not let the player just use their portals to spray the gel akin to how it's done in the Underground chapters of Portal 2?

Interesting, but tedious. Thanks for your effort.

404 on the 1 elevator at the map

What commands do you need to get the elevator moving?

First elevator's broke. Had to use the console to get it moving.

Painted the rooms completely! Fun test chamber!

Very nice, the only problem is it's not clear how to move around, I only worked it out when I came here to see if anyone had said, went back to the game and hit S accidentally.
Also, it's possible to skip the first with portals (which I did do until I worked out how to operate the paint gun and restarted)

The first room is very cool, but challenging, but after I got killed by turrets, I got stuck in the elevator that does not move. Outside of the elevator is pitch black.

This is a really cool map, and the other 2 maps from this series were also pretty cool!
2 things I might add, though: the button on the "Slow" map have a missing texture, and the elevator on this map didn't bring me up at the start. Even with these 2 minor problems, they were pretty nice tests! Looking forwards for more tests from you!

Interesting I thought of doing something like this about 6 months ago but never finished it.
Nice map looking forward to more with this element.
