Play Casper on GBC Online

You play as Casper—yeah, the friendly ghost—in this surprisingly charming Game Boy Color puzzle adventure. Instead of haunting people, you're just trying to make a friend and maybe get a shot at being alive again. Of course, it's not that simple. Carrigan, the greedy new owner of Whipstaff Manor, is tearing the place apart looking for hidden treasure, and your ghostly uncles (Stretch, Stinkie, and Fatso) keep messing things up by scaring everyone.

The puzzles are the real star here—you’ll shift between different ghost forms to move objects, sneak past obstacles, and even possess stuff when needed. The 3D-ish perspective takes some getting used to, but once you figure out how to float through walls without getting stuck, it clicks. Dr. Harvey shows up to help now and then, which is good because those uncles are relentless. It’s a weird little game, but if you liked the movie, it’s got that same mix of spooky and sweet.
