How to play mp3アップ型音ゲー
Upload an MP3 file and tap falling notes in time with your music to score as many points as possible.
On the title screen, upload any MP3 file from your device. The game reads the audio and automatically generates a note chart synced to that song, turning your music into a playable rhythm game.
Notes fall down lanes on a 3D tilted playfield. Tap the lane buttons at the bottom of the screen at the moment each note reaches them. The lanes light up when you press them, giving you visual feedback on your timing.
Each tap is graded on accuracy — PERFECT, GREAT, or a lower grade — and your score increases with each hit. Consecutive hits build a combo, and bonus points are added on top of your base grade score. A Fever multiplier can further boost your score during hot streaks.
After the song ends you see a results screen showing your score and your all-time best alongside the theoretical maximum score. You can also play Endless (survival) mode, where songs keep coming and you try to last as long as possible without stopping.
