Code Breaker is an old Codename: Kids Next Door Flash game on the Cartoon Network website. It's a color sequence game with no other gameplay than to pick colors on a board.
The story is that Stickybeard has gotten into the tree house, and as the player is chasing after him, he closes every door he runs through. The player must open each door to finally catch him.
Gameplay[]
The player faces a number of doors with color combination locks. The members of Sector V tell the player to watch the color sequence and then repeat it to unlock the door. There are five colors to use: green, blue, purple, red and orange. The player has three lives (sweets) and inputting the wrong sequence costs the player one life and sets them back one door. Losing three times ends the game with "Game Over" written on a door. Winning the game results in capturing Stickybeard.
