The pjsekai in Scratch

The official name is “Project Sekai Colorful Stage! feat. Hatsune Miku,” a mobile game. It’s affectionately known as “Proseka.” The game features fun events like event rankings (commonly called “Iberan”), and it’s a popular genre that gets a lot of excitement with each update.
There are skilled creators on Scratch making rhythm games based on it, so I will carefully select the best ones here.

Press the space key to try deleting notes. Some functions, like holding down to delete, might not work – this is just a test. The creator doesn’t know much about Proseka and just watched some videos for inspiration. The background music is "The Disappearance of Hatsune Miku" by Bousou-P. Note syncing isn't planned, as it’s just a test project.
What’s ready: note movement, stage programming, and a beta version for deleting notes. Feedback on the note-deleting code is appreciated.

Play this rhythm game by hitting keys as notes fall to match the rhythm. Choose a song and difficulty level, then press the corresponding keys when the notes reach the bar below. There are three note types: regular, long, and flick, each requiring different timing. Your goal: finish with fewer than 20 misses to clear each song. PC is recommended for easier play. Save your progress using the button in the bottom-right corner, but data resets if you refresh. For a smoother experience, play in Turbowarp (link provided).
