Tag delivers an innovative approach to multiple genres—platformer, puzzle, and first-person shooter—by allowing the player to manipulate the physical attributes of the game's environment using different colors of paint. this was not made by me this was made by digipen
Loved the concept, and the music made things even better. However, it could get a bit frusterationg at times.
@Jok3r098 Portal 2 did not steal the Gel system from this game. However, the Tag Team was hired by Valve to aid in the development of Portal 2. You can kinda tell because in the developer commentary for Portal 2 you can hear some of the developers of Tag.
