If you grew up watching The Grim Adventures of Billy & Mandy, this GBA game nails that weird, darkly funny vibe. You start off as either Billy (clueless but weirdly strong) or Mandy (tiny but terrifying), with Grim reluctantly tagging along—just like the show. The first level throws you right into a graveyard, smacking zombies with a shovel or using Grim’s scythe to slice through obstacles. The controls are simple, but some of the puzzles actually make you stop and think (or, in Billy’s case, mash buttons until something works).

The art style’s spot-on, with those exaggerated cartoon faces and creepy-cute backgrounds. There’s even a level where you’re stuck inside Billy’s nightmare, dodging giant evil clowns—because of course there is. It’s not a super long game, but it’s packed with dumb jokes and little references fans’ll recognize. Just don’t expect Grim to be happy about any of it.
