Snake 2D

A rebuilt take on the arcade classic — play solo, or head-to-head with a friend on one keyboard. The snake never stops moving and accelerates as it grows, so every pickup raises the stakes.

Architecture & design patterns

• Template Method via inheritance — Player1 and Player2 both extend PlayerController and override a single PlayerInput() hook, so grid movement, growth and collision handling are written once and only the key bindings differ (arrows vs WASD)
• Singleton with cross-scene persistence — SoundManager guards a static Instance and calls DontDestroyOnLoad, exposing an enum-to-AudioClip table so music and effects survive scene changes
• Coroutine-based spawning — SpawnFood(prefab, delay) schedules apples, skulls and power-ups on randomised timers at random points inside a BoxCollider2D play boundary
• Enum-typed power-ups — PowerUpType { Egg, Potion, Meat } selects the effect applied to the player, including a shield flag that changes collision outcomes
• List-backed body model — the snake body is a List<GameObject> of segments appended on eat and trimmed on damage, with each segment stepping toward the previous one's target position

Versus rules are resolved through trigger collisions: bite another player and they're out, while a head-on crash eliminates whoever has the lower score. Built while training with the Outscal community.
