Welcome to Lexy's Labyrinth, an exciting old-school tile-based puzzle adventure that is compatible with — but legally distinct from! — Chip's Challenge and its long-awaited sequel Chip's Challenge 2.

This is a reimplementation from scratch of the game and uses none of its original code or assets. It aims to match the behavior of the Steam releases (sans obvious bugs), since those are now the canonical versions of the game, but compatibility settings aren't off the table.

The default level pack is the community-made Chip's Challenge Level Pack 1, which I had no hand in whatsoever; please follow the link for full attribution.
