Tag: The Power of Paint is a 2008 puzzle-platform game. The game was developed for Microsoft Windows by Tag Team, a group of students from the DigiPen Institute of Technology. The game's core mechanics is the use of a special paint sprayed from the player's paint gun to impart physical properties to surfaces, which, in turn, affect the user's movement. Tag won the Independent Games Festival Student Showcase award in the same year. The project team was hired by Valve, using the concepts of Tag as new puzzle elements in their game Portal 2.
