Dear Little Fish:
- Some optimization and bugfix.

Fish Go.io is a massively multiplayer online (MMO) game where players control a small fish and compete against other players in a vast underwater arena. The core gameplay revolves around growing your fish by consuming food pellets scattered throughout the environment and, more importantly, by eating smaller fish controlled by other players. As your fish consumes food and other fish, it grows in size, making it both more powerful and a larger target.

The objective is to become the largest fish in the arena and dominate the leaderboard. Strategic maneuvering is crucial, as larger fish can easily consume smaller ones. Players must use their fish's speed and agility to outmaneuver opponents, avoid being eaten, and position themselves to ambush smaller fish. The game often involves alliances and betrayals as players temporarily team up to take down larger threats, only to turn on each other once the common enemy is eliminated. The "io" suffix indicates that the game is typically browser-based and focuses on simple, accessible gameplay with a large player base competing in real-time.
