Sprunki Phase 4: Decay by the Day

Sprunki Phase 4: Decay by the Day is a horror-inspired music mod where sounds unravel into haunting decay. Create eerie tracks and unlock hidden secrets.

Sprunki Phase 4: Decay by the Day is a chillingly creative music mod developed by Marcello/pan that reimagines the original Sprunki formula with a horror-inspired decay theme. Instead of vibrant beats and playful visuals, this version immerses players in a world of eroding soundscapes, fractured melodies, and ghostly aesthetics. Each character has a haunting design, and their sounds gradually deteriorate, bringing an unsettling beauty to your custom tracks.

A HAUNTING MUSIC EXPERIENCE

The gameplay in Sprunki Phase 4: Decay by the Day stays true to the classic drag-and-drop music mixing style, but with a chilling twist. Each character you add to your track introduces sounds that slowly distort, break down, and transform, giving your mix an eerie, unpredictable edge. Instead of static loops, the audio continuously changes, resulting in haunting, evolving soundscapes that make every session unique.

Key elements include

Haunting sound design - Fragmented rhythms, ghostly whispers, glitching effects, and crumbling beats.
Evolving visuals - Characters visually decay, reflecting their fading sounds.
Hidden anomalies - Unlock eerie visual glitches and secret sub-harmonic sequences by discovering special combinations.
Immersive atmosphere - Every session feels different, capturing themes of loss, entropy, and transformation.
