Lexy's Labyrinth

Lexy's Labyrinth is a re-implementation of the classic puzzle game Chip's Challenge, but completely free and open source, with entirely new art, music, and sound effects, and preloaded with 800 or so community-made levels. You can also play the original levels from the original first two games if you have the original game files.

You play as a fox named Lexy who navigates mazes, finds keys, collects hearts, and pushes blocks around to get through each level.
