Colours is a co-op and single player map pack for Portal 2 which features custom textures, sounds, and a whole lot of fun puzzles which focus entirely on synesthesia, puzzle solving, and cooperation. Features custom music, sounds, and more. Each map will be released as it is completed in order creating a chronologically episodic release, where each map will link to the next and if it does not then it simply resets.

ball catcher?
Yep, but they forget to put the spotlight there, and connect it to the catcher_trigger, if the spotlight is not there, people will think the pellet catcher is disabled.
