A modern Go implementation of the classic typing game Letter Invaders.

This is a rewrite of the classic C version using Go and the Bubble Tea TUI framework. The original game had ~2000+ lines of C code with manual terminal handling - this version is ~300 lines of clean, modern Go.

• Type falling words before they reach the bottom
• Progressive difficulty with level increases
• Score tracking and WPM calculation
• Clean terminal UI with highlighted words
• Pause/resume functionality
• ASCII explosion effect when words are completed
• Configurable speed control for younger players (-speed)

go build

# Run with default dictionary (uses /usr/share/dict/words)
./letter-invaders-go

# Use the short words dictionary (great for kids!)
./letter-invaders-go -d short_words.txt

# Use a custom dictionary
./letter-invaders-go -d /path/to/dictionary.txt

# Slow the game down (milliseconds per tick; higher = slower)
./letter-invaders-go -speed 2000

• Type letters - Match and destroy falling words
• Backspace - Clear current input
• SPACE - Pause/resume game
• Ctrl+L - Redraw screen
• Ctrl+C - Quit (use q on the Game Over screen)

The dictionary file should contain one word per line. The included short_words.txt contains 1-3 letter words, perfect for beginners and young children.

Based on the original Letter Invaders by Larry Moss (1991)
