Extensions

Lexy's Labyrinth has a few extra features not present in any canonical version of Chip's Challenge.

New play features

LL has rewind and undo, which have never been present in CC. (As a nod to this, your score for a level shows a star if you beat it without using rewind or undo.)

LL supports custom camera regions, which lock the camera to within a given rectangle as long as the player is within that rectangle. Useful for levels made out of multiple small rooms from which the others aren't meant to be visible, or levels that have machinery outside of the play area that's awkward to hide. Please use responsibly.

They are stored in a custom LXCM lump, each one encoded as four bytes: x, y, width, height.

The behavior of overlapping camera regions is currently undefined, though in the future may be extended to make L-shaped camera regions possible.
