: Since the game requires local files, you can use Audacity to record audio from streaming desktop apps. Use the Windows WASAPI host and set the recording device to your loopback speakers/headphones.
: Advanced users can edit .sync files. The format includes version info, song length (seconds/units), BPM, and confidence scores. It also maps transitions (Low, Normal, High, Explode) and specific obstacle time-points. Custom Skins & Modding
: Play 100 tracks. You can automate this by selecting your music folder on "Relaxing" difficulty and letting it play through, only needing to press continue between songs.
: The game supports 4K Ultra HD and offers windowed or borderless options. If your monitor is wider than 16:9, expect stretching or pillarboxing. Adding & Syncing Music
: Custom skins should be placed in the Steam\SteamApps\common\MelodysEscape\CustomSkins folder. Each skin folder typically contains a sprite-sheet.
