About this game
Keystones challenges you to think in three dimensions. Your objective is simple: navigate voxel structures to their designated targets. However, achieving this requires mastering a specific set of spatial movement mechanics.
Core Mechanics
Slide: Move blocks linearly across the grid to reposition them for the next move.
Rotate: Pivot objects around their axis to change their orientation and fit into tight spaces.
Tumble: Roll blocks onto their sides to traverse the grid, shifting their footprint with every move.
Key Features
Cerebral Gameplay: No timers, no stress. Every move is a deliberate choice in a purely logic-driven environment.
Voxel-Based Logic: Interact with clean, grid-aligned structures designed for maximum clarity and precision.
Increasing Complexity: Start with simple navigation and progress to complex multi-step puzzles involving color-based validation and spatial constraints.
Atmospheric Experience: A focused, minimalist aesthetic designed to keep your attention on the puzzle solving.
