Snake (Python + Tkinter)

A modern take on the classic Snake arcade game, built with Python and Tkinter. It includes dynamic themes (Classic, Ocean, Sunset, Retro), animated title reveal, score + session high score, and a reset flow from a Game Over screen.

---

Features

• 4 themes via dropdown: Classic / Ocean / Sunset / Retro
• Animated title and start prompt
• Arrow-key controls with smooth, timer-based movement
• Score + session high score (resets when the app closes)
• Reset button shown on Game Over
• Window-centering and fixed-size canvas (1000×700)

---

Controls

• Space — Start the game
• Arrow Keys — Move (Up/Down/Left/Right)
• Theme menu — Change theme (resets the game)
• Reset button — Appears after Game Over

Note: WASD and pause aren’t implemented in the current code.

---

Requirements

• Python 3.8+
• Tkinter (bundled with most Python installers)
  • Linux: you may need to install it separately, e.g. sudo apt install python3-tk

How It Works (quick tour)

• Constants: tune board size, speed, and cell size at the top of snake.py
• Themes: managed by THEMES + apply_theme(theme_name) which resets the game, recolors the canvas, and redraws the snake/food.
• Game loop: next_turn() updates the snake’s head position, handles growth when eating food, and checks collisions before scheduling the next tick.
• Entities:
  • Snake class stores coordinates and canvas rectangles
  • Food class spawns a new food circle at a random grid location
• Input: Arrow keys are bound via window.bind(...); Space starts the run.
• Game Over: clears the canvas, shows a Game Over banner, and a Reset Game button that re-applies the current theme.

---

Customize

• Add a theme: extend THEMES:

  THEMES["Neon"] = {"bg": "#0A0A0A", "snake": "#39FF14", "food": "#FF2079"}

  It will automatically appear in the dropdown.
• Change speed or grid: tweak SPEED and SPACE_SIZE.
• Board size: update GAME_WIDTH / GAME_HEIGHT.

Roadmap / Ideas

• Pause/resume (P)
• WASD support + key repeat throttling
• Persistent high scores (JSON or SQLite)
• Sounds and music
• Difficulty levels
• Obstacles and power-ups
