Plumb Pile: Stack Against the Drift

Core Gameplay
Players stack blocks while a plumb line (vertical string with a weight) hangs from the top of the screen. The goal is to keep the stack aligned with the plumb line within 5 degrees. The twist: the plumb line sways slightly due to invisible air currents, which change direction every 10 seconds. Players must adjust stacking positions accordingly.

Level & Content Design
240 levels with increasing current strength (from barely noticeable to strong drift). Special “Crosswind” levels have two opposing currents, creating a standing wave pattern. All levels are pre‑loaded; no live data required.

Visuals & Experience
Seafaring theme – wooden scales, rope textures, brass details. The plumb line is a shiny metal bob. The background shows gentle ocean waves matching the current strength. Sound includes creaking ropes when the line sways.

Key Features

Drift Predictor: A translucent cone showing where the plumb line will be in 3 seconds.

Anchor Mode: Lock the plumb line for 5 seconds (once per level).

Local High Scores: Best height achieved for each level, stored per device.

User Value
Improves anticipation of moving targets and environmental adaptation. The drifting plumb line adds a subtle but engaging layer of difficulty.

Usage Scenarios
Great for after‑lunch mental sharpening, or as a light challenge while riding as a passenger in a vehicle (the drift mimics motion sickness without the sickness).
