Tile World is an emulation of the game "Chip's Challenge". "Chip's Challenge" was originally written
for the Atari Lynx by Chuck Sommerville, and was later ported to MS Windows by Microsoft (among other ports).
See http://www.muppetlabs.com/%7Ebreadbox/software/tworld for details.
Here is a port on Pandora of latest version 1.3. This package does not come with the chips.dat file
that contains the original level set. This file is copyrighted and cannot be freely distributed.
