How it works
• Two-digit hex numbers drop from the top as invaders.
• Flip the 8 bits at the bottom so the byte equals an invader's value — it explodes and you score.
• Bits are MSB → LSB (left = 128, right = 1). Convert
• If any invader reaches the bit row you lose a life. 3 lives, then game over.
• Invaders fall faster and spawn more often as your score climbs.
Controls
• Click / tap a bit cell to toggle it.
• Keys 1–8 toggle bits left → right.
• Backspace clears all bits, Space starts / restarts.
Goal — practice fast hex → binary conversion under pressure.
