Picture packs

Choosing a pack restarts the game. Each pack keeps its own best score. In image packs, double-click (double-tap) a picture to rename it; in custom packs, click two pictures to swap their order (their sounds move with them).
Chain sounds (played when a chain continues with that face): ♪ sound supplied by the pack · ♫ built-in default. Tap a button to preview.
Pick 2–12 images, plus optional sounds with matching numbers (1.png + 1.mp3, 2.png + 2.m4a, …; played in full; clips over 30 s are cut to 30 s), or drag & drop them onto the window. Ordered by file name, smallest tier first. White backgrounds are removed automatically. You can also pick an exported pack file (.json). Background music: add audio files whose name starts with bgm (bgm.mp3, bgm-2.mp3…, up to 4, max 8 MB each); one is picked at random each game.
