About
Chip's Challenge is a 1989 top-down tile-based puzzle game originally published by Epyx as a launch title for the Atari Lynx, later ported to several systems including bundled Windows releases where it found a much wider audience. Tile World 2 is an emulation of the Chip's Challenge game engine (not the original level data) for Linux, Windows, and macOS, built with CMake, SDL2, and Qt5/6, and improving on the original Tile World's user interface. It ships with six free community-made levelsets (an intro set plus CCLP1-5) and supports custom levels via level editors.
How it differs from the original
It does not include the original copyrighted Chip's Challenge level file (CHIPS.dat) — players who own it can copy it in to play the original levels, while everyone else plays using the six free community-made levelsets bundled with the project instead.
Getting started
Build from source with CMake (needs a C compiler plus the SDL2 and Qt5/6 libraries) or use the prebuilt Windows release; copy any .dat levelset files into the data folder and they'll appear automatically in the main menu.
History
Tile World was originally written by Brian Raiter; Tile World 2, which specifically refined the original's user interface, was developed by Madhav Shanbhag, with later versions (2.1, then 2.3) produced by other contributors.
