Fixed a minor bug.

The results screen now displays recommended songs. Bugs that prevented songs from loading have been fixed.

Regarding the issue where notes overlapping by a second were difficult to read, we have improved it by displaying them separately on the left and right sides from the stem, similar to standard musical notation. I have corrected and improved the processing that caused the "Tie" icon to appear as a lingering image when a "GREAT" result was determined.

We've adjusted the sheet music layout to more closely resemble actual musical notation. We've added spaces between the bar lines. You can revert to the original display from the performance settings screen.

I've added a feature to create sheet music. You can create up to 32 beats and 64 notes per score for free, and unlimited scores are available with the premium plan.

I've added a share button for each individual piece.

Added a pause function for playing. You can now restart playing from the beginning midway through. Added a function to switch to landscape mode on the playback screen even if the smartphone's orientation is fixed.

I've added a feature that displays a list of songs related to the stage and other recommended songs.

Significantly improved performance. Adjusted the layout of the stage list and settings screen. Added support for Alto and Tenor symbols. Adjusted the keyboard note names to match the note names.

A "Continue Playing" function has been added to the home screen to make it easier to resume playing the song you were previously playing. If you have already completed a song, recommended songs will be displayed. Other minor bugs have also been fixed.

A level-up gauge has been added to the results screen. A list of stages unlocked upon leveling up is now displayed. Days with activity are now highlighted in the daily history on My Page. Other minor bug fixes and animation optimizations have been implemented.

I've added a "Practice Mode" that lets you play while checking each note. Just like in normal mode, the musical staff scrolls by, but in this mode, the music pauses when a note appears, and playback stops until you press the correct key. Once you've pressed the correct key, playback resumes to the next note. While you'll earn less XP in Practice Mode, you can gradually increase your level, so please give it a try!
