Remember that episode of Jimmy Neutron where he teams up with Jet Fusion? This GBA game basically turns that into a full-blown adventure. You're running around Retroville, zapping weird little alien creatures with Jimmy's gadgets, and yeah—Professor Calamitous is up to his usual nonsense. The puzzles aren't brain-melting, but some of them actually make you stop and think, like when you've gotta rewire something or outsmart a security bot.

It's got that classic early 2000s cartoon look, all bright colors and exaggerated animations. The controls are simple—jump, shoot, tinker—but the levels mix things up enough that it doesn't get stale. And honestly, hearing Jimmy's voice lines when you pick up an item or solve a puzzle? Pure nostalgia. If you grew up watching the show, this one's a weirdly specific time capsule.

Just don't expect some deep RPG or anything. It's a solid little action-puzzler that knows exactly what it is. You'll probably blast through it in a weekend.
