About Jimmy Neutron Vs. Jimmy Negatron (prototype)

I found a prototype of Jimmy Neutron Vs. Jimmy Negatron for the Game Boy Advance, a game that never got an official release. It was developed by Human Soft, the same team behind the other Jimmy Neutron GBA titles. This was during the peak of licensed platformers on the handheld, where you'd often see cartoon characters navigating side scrolling levels.

You control Jimmy Neutron, running and jumping through themed stages like Retroville and space. The main goal is to stop your evil clone, Negatron, by progressing through each level to reach a boss fight. Your primary actions are jumping on enemies or using a simple blaster to shoot them. You also collect bolts scattered everywhere, which act as the game's currency, and find health pickups to survive longer. The pacing is straightforward, but some enemy placements and platforming sections can be surprisingly tricky. Playing it feels like a quick, unpolished dash through a familiar cartoon world.
