Stack Signal

Stack Signal is a touch-first falling-block micro for Falling Block Jam 2026. Pieces land in a 6-wide well with amber or tomato pulse phases; a full line clears only when every cell shares the same phase—mismatched rows stay locked until you match them. Clear the quota across 8 short rooms before the stack tops out.

Made during Falling Block Jam 2026.

Controls: arrow keys / swipe to move, Z or tap to rotate, X or ⇄ to flip phase, soft/hard drop. On-screen buttons on touch.

No generative-AI art or audio.
