There's now a pair of Steam games related to this one that are out and available for purchase: Chip's Challenge 2 (the sequel to this game) and Chip's Challenge 1 (the original Chip's Challenge levels in the CC2 engine, minus the ability to drop items at will). Chip's Challenge 2 probably needs to be a separate game, but how will CC1 be handled?

CC1 in the CC2 engine will be a category under CC2. Sorry I didn't respond to this sooner, I didn't see this until now.
