Mirror Bit

Mirror Bit is a webcam rhythm game built for players who have one arm.
Your camera tracks your body, and the game mirrors your real arm into a glowing hologram arm on the other side, so you get to punch, dodge and play with both.

It's mirror therapy, a technique used in rehabilitation, turned into an arcade workout.
No controller. No keyboard. Just you.

Real player, real gameplay: one arm behind her back, the mirror arm does the rest.

Stand up and move to the music.

• 👊 Punch the blocks on the beat: blue blocks need a fist, purple ones an open hand
• 🪞 Your mirror arm hits too: every move of your real arm is copied to the other side
• 🧱 Dodge, duck and jump over the red walls, and it gets harder in the chorus
• 💥 Smash the green wall with a flurry of punches before time runs out
• 🔥 A real workout: a live calorie counter and goal on screen

Hands on the table: mirror therapy you can play.

• ✋ 5 hand shapes: fist, open hand, thumbs up, call me and side hand
• 🎯 Make the shape when the button reaches the glowing line
• 🪞 The mirror hand copies yours, standing in for the hand you don't have
• 🧠 The game learns your hand at the start, and the levels speed up as you get better

• Pick your missing arm: left, right, or play with both arms
• Find-your-spot camera guide and a quick practice round before every mode
• PERFECT / GREAT / GOOD timing, combos and multipliers up to x8
• Results screen with your grade, records and daily progress
• Pause, settings and volume, plus an option to turn jump walls off
• Original soundtrack composed for the game by a real human musician
