A retro terminal-based Battleship game. Sink the enemy fleet before they sink yours.

---

How to Run

node game.js

Requires Node.js 18+. Zero external dependencies.

How to Play

1. Place your fleet on the grid, one ship at a time.
2. Take turns firing shots at the enemy grid.
3. Hits are marked red, misses are marked blue.
4. Sink all five enemy ships to win. Don't let them sink yours first.

Arrow keys	Navigate cursor / menu
Enter	Confirm / Fire
R	Rotate ship (during placement)
Escape	Back / Cancel

Game Phases

Placement	Position your five ships on the 10x10 grid

Difficulty Levels

Level	Fleet	Islands	AI Behavior
Easy	6 ships (19 cells)	4 island clusters	Fires randomly
Medium	5 ships (17 cells)	None	Hunts adjacent cells after a hit
Hard	4 ships (12 cells)	8 scattered islands	Follows ship axis after consecutive hits

Ships

Ships vary by difficulty. Medium uses the classic fleet:

Ship	Size
Carrier	5
Battleship	4
Cruiser	3
Submarine	3
Destroyer	2

Easy adds a second Destroyer (size 2). Hard drops the Carrier.

Highscores

Scores are saved to highscores.json in the project directory. Viewable from the main menu. Ranked by fewest turns -- efficiency wins.

Technical

Built with Node.js. Zero external dependencies. Renders entirely through ANSI escape codes in your terminal. No frameworks, no libraries, just raw stdin/stdout.
