PulseShift

Harmonic Shift is a puzzle game that blends visual reasoning with musical feedback. Each level presents a grid of colored cells, each paired with a unique musical note. Your goal is to shift rows and columns to align every row with its target color sequence.

Start with simple 4x4 grids using two colors and tones. As you progress through 30 levels, the challenge grows: larger grids up to 6x6, four or more colors, fixed cells that cannot be moved, and cross-target rows requiring different patterns. Each level gives you a limited number of moves to find the solution.

Features:
- 30 progressively challenging levels
- Grid sizes from 4x4 to 6x6
- Musical note feedback for each move
- Step limit adds strategic pressure
- Visual glow effects on matched rows
- Fixed cells and cross-target mechanics in later levels
- Infinite Mode unlocked after completing all 30 levels
- Best score tracking for each level
- Sound effects toggle

Every shift produces a tone, turning spatial reasoning into an audible experience. The clean, minimalist design keeps you focused on the puzzle. No ads, no permissions, no internet required.
