How to Play

To play, watch for floating arrow symbols that appear above the brother on the right side of the screen. When an arrow shows up, press the matching arrow key on your keyboard to hit the note.

Practice your timing and enjoy the musical duel.

Tips for Success

Focus on the rhythm of the music to anticipate the timing of each arrow. Start by playing at slower speeds to build muscle memory for the arrow patterns. If you miss a note, don't panic—just refocus on the next one to avoid a chain of misses. Take short breaks between rounds to keep your reflexes sharp. Practice regularly with different songs to improve your overall timing and accuracy.
