Shark! Shark! for the Mattel Intellivision

As a classic arcade simulator originally released in 1982, Shark! Shark! puts you in control of a fish whose goal is survival and high-score accumulation. The core loop involves eating smaller fish to grow larger, which unlocks the ability to consume bigger prey, but beware: anything larger than you is lethal. A key feature is the fast shark; you can earn points by repeatedly attacking its tail, though this is risky. Progression is tied to scoring milestones, which increase your fish's size, and the game supports both one and two-player modes across various speeds.
