Tyler is a puzzle game developed by Ugly Dog Software in 1995. In the shareware version played here, players need to navigate a purple orb named Tyler through 10 stages starting from the green tile, while touching every grey tile, which fades out shortly after being stepped on, then reach the red tile after doing so. There are also teleport tiles which warp Tyler to a different tile, as well as obstacles, which need to be dodged. The full version is said to contain 30 stages in total.
MUGG navigates through all 10 stages from the shareware release in record time.
