Chuck Sommerville is the original creator of Chip's Challenge, as well as the designer of many CC1 levels. He is credited for the 8 lesson levels, as well as On the Rocks. He also created a sequel, Chip's Challenge 2, but was unreleased for years due to copyright issues. For this reason, CCLP2 was created as an unofficial replacement. Meanwhile, Chuck took a leaf out of Brian Raiter's book and is developing the Tile World equivalent to the original CC2: Puzzle Studio. Like Tile World, as this uses different coding and graphics than the original, it will be a legal copy. However, CC2 was released on May 28, 2015.
