The portal gun is gone, the paint gun is your new tool.
Aperture Tag is a short Portal 2 mod that finally allows you to completely cover any puzzle with blue paint.

This mod heavily focuses on puzzles, there's no story though you still have your funny robot supervisor following you.
As you probably already guessed, the puzzles are mainly based on platforming (nothing unfair though). They are not very difficult but still use a couple of smart paint tricks, and it can be hard to find the correct path.
The paint gun is also restricted, you have to walk though barriers that allow blue and/or orange paint before you can use it.

Not much else to say, there's a very fun pure platforming section midway through the game that I really liked (they put a skip button for people that find it too hard, you won't be stuck).

Aperture Tag is a pretty good mod and I recommend it (1€ on sale).

me and nigel in the citrus club straight up paining it heh

Makes me miss the portal gun
