Candyland Surfing (cancelled Atari 2600 game)

Candyland Surfing was an Atari 2600 game by former 20th Century Fox programmer John Marvin, who has said that the game was based around a technical effect that would happen by changing the colors on the scan lines ton get a rainbow effect. It ended up being cancelled because there wasn't much gameplay to it as it was more like a screensaver. No ROMs of the game have circulated as of yet, & will remain unlikely.
